On/Off Round Key Lock - 12mm Diameter

Mechanical Key Lock Switch for On/Off Control

This compact and low-cost key lock switch operates using a literal key instead of buttons or levers. Insert the 'bike lock' style key into the 12mm diameter hole, rotate it clockwise to electrically connect the two contacts on the back and activate the switch. Rotate the key counterclockwise to disconnect and turn off. The key can be removed in either position, making it excellent for an 'On-Off' switch requiring a key to activate.

Important Notes:

• Same key is provided with each order (no unique keys).
• Minimal security; not suitable for high-security applications.
• Compact size requires drilling a 12mm (0.5") diameter hole for mounting.
