MICRO SWITCH GK Series switches are key-operated safety interlock rugged metal switches which monitor the positions of gates, guards, or doors. The key is attached to the moving portion of the gate, guard, or door. When the gate is closed, the key is inserted into the GK switch indicating a safe position (gate closed) and the machine process can start. The positive opening normally closed contacts are held closed when the key is inserted into the GK switch. Opening the gate, removes the key from the switch. This action opens the normally closed contacts of the switch and interrupts the machine's control circuit.

GK Series switches are designed with dual-entry positions for the key. The key can be inserted from the top or side of the switch which allows more flexibility in mounting the switch in the application. There are four different styles of keys and a variety of switch contact arrangements to satisfy the requirements for most applications requiring a safety interlock key switch. GK Series switches are designed with a unique friction feature for key retention. GK Series switches have been evaluated for safety functions up to and including a safety integrity level (SIL) of SIL3 when evaluated to the requirements of IEC 61508-2:2010.
