    This was probably a prototype/proof of concept. I worked with a few large machines and all doors were secured with locks just like this one, the switch thrown by the mechanism functions as a redundant emergency stop to ensure nobody can bypass the open door and turn the machine on, since a person could be inside. They're usually dressed up in thick plastic and have a more industrial looking key

    Ooooo, I might actually have an idea on this one! As a controls engineer, I have some experience with this type of stuff (albeit most stuff has specialty hardware for applications like this). My guess is that the solenoid would be used for checking if a high speed motor is spinning. On some grinder systems, it can take upwards of 10-30 min to stop spinning after you stop powering the motor, and hooking the solenoid up against the motor (checking if it is acting like a generator) would allow you to ensure the motor is actually stopped before the key can be removed, and the key being removed could then disable the start signal to the motor. That may not be it exactly, but I would bet significant money it has to do with some physical force acting on an electric system via momentum, could be something flow related as well acting off pressure or even temperature related.

    Such devices are in use also in (petro)chemical industry, in continuous processes, where you dont want to shutdown everything, bc one part has a (hopefully) temporary problem. For instance, a number of cracker installations, feed a compressor, that feeds a cold section, where fractions are separated. If the compressor trips for some reason, you do not immediately shutdown the entire factory, bc that is very costly. An electrical detection gives an electrical signal to your key, which can then be turned to allow another electrical signal, which opens valves, which directs cracker output from the compressor to a flare. You wouldnt want the key turned in normal operation. It will usually be an emergency operation that can be automated, but the key is leaving a human decision in the chain.

    I work for an electric utility. We use these in substations on high voltage circuit breakers. The breaker has to be open to energize the solenoid to turn the key. The contacts stop the breaker from being closed electrically with the key removed. The key can then be moved to allow a manual disconnect switch to be opened. We don't want these switches to be opened under load and having that key in hand means the breaker is open, therefore no load on the switch.

    I've seen similar things in an icecream factory I worked summer-shifts in back in the day ('96-'01). Huge stainless steel cauldrons of fast moving mechanical parts that need to be cleaned every day, but have no way to be disassembled properly without being busy for hours, so only the bowl is removed with the moving, mixing parts attached to the machine. You disengage it from the mains with a key. I remember the slight humming sound when operating the key(s), probably some arcing effect.

    If I had to guess that would have been one half of a set of two identical locks. One would be the “Lockout” and the other would be “Operate”. When you want to start the device you turn the “Lockout” key off (throwing the switch) which unlocks the Solenoid on the “Operate” switch, you then take the key from the “Lockout” switch and transfer it to the “Operate” switch then turn on that switch which would engage the Solenoid on the “Lockout” switch so it couldn’t accidentally be engaged. I saw something similar in a Power Substation once, however that one also was a mechanical lock to prevent the door from being opened while the station was operating.

It's just politeness and they don't actually care if you have a nice day and you donut care if they have a nice day either. But for some reason today watching this I actually feel like you actually are wishing us a nice day. And I really needed that. Thank you LPL for wishing us a nice day.

    We see interlocks like that on 13.800V gear here, you have to shut the section off, before the key will work, and the other switch will not allow current to allow you to pump it up and close the circuit until the door is closed and locked, have had to "by pass" a few over the years to troubleshoot equipment.

    Ahhh Yes @LockPickingLawyer The infamous “Kirk Keys”. So if you don’t know about this company go check out their website, their product is used in many safety applications across the industry. Especially in the electrical industry in substations to prevent inadvertent switching of high-voltage circuits or to enter a cage or a restricted area at a plant or a transformer room where multiple keys will have to be used by different key holders in a sequence to allow the lock or breaker or to gain access to some thing or some location. I have seen photos of Kirk key installations requiring no less than 9 to 15 keys don’t ask me I can’t tell you where they are 🤔

Turn the key the other way and a switch will make the metal rod retract to open the door.

    It's to stop an operator from turning on a machine while the power is off. For example: Two employees are working on an industrial saw which is on, but unplugged. The one working on the blade is near the switch which they are used to activating in order to use the machine. Another employee plugs in the saw. Bad things happen. This device makes sure that the machine can only be turned on when power is supplied to it.

    We used to use pretty much this exact setup at the National Synchrotron Light Source. The key and capture device was part of the safety interlock system. The experimental area, called a hutch, would be searched. The door would be closed and locked and then the key would be transferred to this device where it would be captured. You couldn't remove the key without pushing the button. With the key properly in place, you could open the photon shutter and allow beam into the hutch for the experiment. When the beam was on, you could not remove the key. The key removal button was deactivated. To remove the key, you had to close the shutter and turn off then beam, which would activate the button. The facility was built in the early 80's and was decommissioned in 2014. I wouldn't be surprised if this was actually one of ours that someone saved as a souvenir.

    This is commonly called a 'Kirk Key'. There is only one key and more than one lock so only one lock can be open at any given time. One use would be a facility that has a generator but no transfer switch. There would be Kirk Keys on the power company main and the generator main. This would prevent the generator from back feeding the power company lines (and creating a very serious hazard for anyone working on the lines). Another one I see a lot is a circuit breaker and a door to the inside of whatever the breaker is powering. You have to have the breaker off in order to open the door.

    Looks like a interlock system I saw demoed at an electrical substation. IIRC, it was on a capacitor bank. There was a timer that prevented you from pulling the key out of an assembly similar to this one for a few minutes after disconnecting the main feed. After the timer elapsed, you could retrieve the key from this lock, and use it to unlock the grounding switches. The time delay would allow the capacitors to discharge before the grounding switch would crowbar them, preventing damage to the switches.

    These are referred to as trapped key interlocks. The solenoid enables the removal of a key, which activates a feedback signal to the control system. The removed key is then used to actuate another key switch or lock somewhere else. At no point can both systems be engaged because of the flow of the locks and key, and at no point can the key be moved until the system permits it. So, yknow someone does enter a machine work cell and get turned into minced meat by activation.

    You cannot open that lock unless some required electrical safety preconditions are met. The machine must be safe to approach before anybody can get in! Some of the conditions could be: The machine is in a lowered down position where it cannot move or fall, hydraulics have been shut off and there is no pressure remaining in the piping, an emergency stop was requested to the drives and they safely assure that nothing is electrically powered in the locked area...

    Wouldn't that pin in the dropped down direction be considered a anti-picking device... or rather, not prevent the rotation of the cylinder, unless power was in the circuit. In the event of power outages, these units will not allow for access, until power is restored ? just a thought... clever system though.. I may have to incorporate something like these at my bunker, on top of the bank vault doors I made... pretty clever, based on how simply this is... Might also be one bad idea also, for end of the world type scenario... electric power being at a limited supply, if at all.. only to then be locked out of your own stuff...lol

    Incredibly common to have electro-mechanical interlocks on high voltage electrical switchgear. Often the solenoid will be linked to a switch board that is not close by. If you accidentally earth a HV circuit it is catastrophic or if you close a switch onto a circuit that maintenance is happening in then it is also life or deaf!

    Kirk-Keyed interlocks usually are used to physically prevent removal of energized breakers from switchgear cells or to prevent bypassing of the switchgear door mechanisms when energized. The 1st electrical connections are remote "permissive" connections to allow operation of the key "locally". It's hard to know what they used it for without a schematic...interesting, though.

    Some interesting info: In the construction we use something called "Lock Out Tag Out". When we work on a potential dangerous energy source (not limited to electric), there must be a way to prevent any single person from activating the energy source. Every single person that works need a lock with their contact information on a tag. These locks go on a multi latch which in turn, lacks a box with a main key. These boxes have multiple of these multi latches attached to them. The master key is the key that physically locks out the energy source in some shape or form. Every lock must be removed before the master key can be accessed.

    This might be used for old switchgear equipments were an interlock prevents someone from accidentally switching the wrong MOD(Motor operated disconnect) this is used because shutting down an entire power grid accidentally is a horrible idea, this is also connected to the E. Stop switch to prevent someone from switching it on. The interlock is also used in substation breakers to prevent someone from turning it on while someone somewhere is working with the lines. It is usually connected to the lockout switch(electrical engineers please correct me)

    this is a kirk key system. they are available in several interesting configurations. i have a very old one that uses 3 chicago locks. i also have a few setups that i removed from some switchgear that was being scrapped from a utility, with all keys and locks in that system. this particular setup is part of a larger system, where likely it is checking one or more breakers or switches to be open to electrically actuate the solenoid to allow the key to rotate, then rotating the key actuates a switch that would possibly trip a downstream (or upstream device) and interrupt its closing circuit. the key is then withdrawn and taken to another lock, which would then unlock a manual cranking mechanism for a disconnect switch, one that may only be operated either deenergized or under a no load condition. this is a hypothetical situation, not sure exactly what the extent of this particular system was originally. but this gives you some idea of a possible application. these are generally used in plants and utilities to ensure that certain orders of operation are strictly adhered to, for worker safety. and youre right, while pickable, GENERALLY procedures in place would have a worker stop what they are doing if the kirk key system doesnt allow them to proceed, rather than defeat the system entirely.

    Professional automation engineer here: In order to access a robotic cell or a machine area, the operator has to press an access button. The access request let the system (robot, machine, ...) stop in a controlled way (this might be what you see on the left side of the lock). When the equipment is stopped, the key is unlocked. The operator would then put the key in his pocket to prevent the cell or machine to be rearmed while still being in a hazardous place. The small switch might be a feedback to the controller letting it know that the key has been turned or it might be a safety switch to disable the system.

    I believe i have at least one example where that KIRK interlock is used. In a UPS "Wrap around" maintenance bypass unit. In large computer room UPS systems (Uninterruptible power supply), often it is necessary to use large switches and breakers to allow the UPS to be fully de powered without breaking power to the computer room. The process is usually similar to: Push button to activate start the process (usually also starts a timer and maintenance in progress alert); After UPS is internally in bypass solenoid allows KIRK key to turn, when key is turned switch sends signal to UPS to enter internal bypass; Human operator removes key; Key is used to unlock large KIRK bolt locks on circuit breakers in sequence that bridges the utility input "around" the UPS unit. Somewhere in my photo collection i have a pic of one of these.

    This is part of an interlock system utilizing several different lockouts for safety. I noticed that the key is captured when in the locked position. This requires that the solenoid gets energized to allow the lock to be rotated and then the key can be removed and preventing someone from operating the switch. I have dealt with this before where several different items had to be turned off, in sequence, before the final key was made available to allow entry into a hazardous area.

    I see a lock like this being used where you have a two person authentication. Say, you walk up to this lock and an intercom (person) asks you to insert your key. You do, then the person throws a switch allowing you to use your key (otherwise it couldn't even be picked) Then, when your key turns, it throws the switch. The switch could either be used to show on a display which doors are open or shut, or also could then allow you to get access to another door.

    Two person key safety interlock. The solenoid is actuated by a "deadman" switch, where the button has to be held down to enable to key to turn. The button is usually located well out of reach of the lock requiring a second person to press the button. The button can be bypassed in any number of ways, opening the enclosure and jumping it with wire, taping a bolt, nut, rock, or other small hard object over the button, or wedging a stick or broom/mop handle between the switch and the wall. Ideally the button would be in some kind of control room with more than one observer.

    Correct me if I am wrong but if the solenoid does not retract then even if you pick the lock then the key will not turn? If this is true then you need access to the solenoid *first* no matter how easy is to pick the lock...
