{"product_id":"on-off-round-key-lock-12mm-diameter","title":"On\/Off Round Key Lock Switch - 12mm Diameter","description":"\u003cp\u003eMAJOR KEY ALERT we now stock 'Key Lock Switches'! These mechanical switches don't use a button, lever, or magnet to open and close the contacts. Instead, a literal key is used. This low-cost but effective key lock switch is nice and compact: you only need to drill a 12mm \/ 0.5\" diameter hole in your mounting plate.\u003c\/p\u003e\n\u003cp\u003eInsert the 'bike lock' style key and rotate it clockwise; now, the two contacts on the back are electrically connected. Rotate it back counterclockwise 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.\u003c\/p\u003e\n\u003cp\u003eIf you want a version of this lock where the key cannot be removed in the On position, \u003ca href=\"\/zh\/products\/momentary-on-off-round-key-lock-switch-12mm-diameter\"\u003echeck out the 'momentary' version of this switch\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note: This is not for use in a nuclear warhead situation - each key lock order comes with the same keys.
