Adafruit On/Off Round Key Lock - 12mm Diameter

MAJOR KEY ALERT 🔑🔑🔑 We now stock 'Key Lock Switches'! These mechanical switches employ a unique operation method using an actual key instead of a button, lever, or magnet to control the contacts.

This cost-effective and compact switch requires only a 12mm or 0.5" diameter hole for installation. Simply insert the 'bike lock' style key and turn it clockwise to connect the contacts. Rotate counterclockwise to disconnect, with the option to remove the key in either position.

Features include a practical 'On-Off' switch functionality with key activation, ideal for minimal security setups or as a fun interface where expert unauthorized access is not a concern. Note: All keys are identical per order, and the lock is not pick-proof.
