Keylock click carries a processed sealed key lock mechanism that can be set in three different positions. The click 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 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.

Code examples for Keylock click, written for MikroElektronika hardware and compilers are available on Libstock.
Code snippet
This is a simple example of how Keylock click works, depending on the state of the Keylock click the appropriate position will be detected.
