Momentary On/Off Round Key Lock Switch - 12mm Diameter

Introducing the Momentary On/Off Round Key Lock Switch, a compact and effective mechanical key switch with a 12mm diameter. Instead of using a button or lever, this switch uses a literal key to open and close the electrical contacts, providing a simple and secure on-off functionality.

To operate, insert the 'bike lock' style key and rotate it one turn clockwise. This connects and locks the two contacts on the back of the switch. Rotate it counter-clockwise to disconnect the switch and remove the key. This momentary style switch does not allow key removal while turned on.

Key Features:

• Requires a 12mm / 0.5" diameter hole for mounting
• Momentary style key lock switch
• Simple On-Off switch activated by key rotation
• Each unit comes with identical keys
• Ideal for fun interfaces or minimal security applications

Note: This is not intended for high-security uses. The lock is easily picked and all switches use the same key.
