On-Off Key Lock Switch – 12mm Diameter

MAJOR KEY ALERT we now stock ‘Key Lock Switches’! These are mechanical switches that don’t use a button, a lever or a magnet to open and close the contacts. Instead, a literal key is used. This is a low-cost but effective key lock switch that’s nice and compact: you only need to drill a 12mm / 0.5′ diameter hole in your mounting plate.

Insert the key and rotate it to the green dot, now the two contacts on the back are electrically connected. Rotate it to the red dot to disconnect the switches. You can remove the key in either position. It makes for an excellent ‘On-Off’ switch that requires the key to activate.

Please note: This is not for use in a nuclear warhead situation – each key lock order comes with the same keys. And it isn’t hard to pick this lock either. Think of this as a fun interface, or minimal security setup where you aren’t concerned with a skilled adversary.
