Overview
The Keylock Click Board™ carries a processed sealed key lock mechanism that can be set in three different positions. The Click Board™ is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over the PWM, INT, and AN pin on the MikroBUS line.
The Keylock Click Board™ comes with two keys and a protective cap for the mechanism.

The key can be removed from the lock in any of the three positions. The package contains two keys and one protective cap.
KEYLOCK FEATURES
The contact mechanism provides unequaled logic-level reliability and smoother, positive detent actuation.
Detent mechanism, with its spring-operated steel ball, gives crisp, positive action for accurate switch setting.
