This is a guard locking safety switch used to secure movable machine guards until it is safe for them to be opened. It combines position sensing with a locking mechanism, preventing access to hazardous areas while a machine is in motion and releasing the guard once a safe state is confirmed. Typical applications include interlocking on guards and access doors within automated production and machinery panels.
