The Schmersal AZ17-11ZRK safety interlock switch uses a key actuator to monitor the position of machine guards and access doors in industrial safety systems. It provides one normally open and one normally closed contact for direct integration into safety circuits, supporting applications that require reliable interlock control on equipment such as conveyors, presses, and automated production lines. The switch’s compact housing accepts the key only when the guard is fully closed, helping enforce safe operating sequences in line with common machinery safety practices.
