Trapped Key Bolt Interlock Switches

Our Bolt Trapped Key Interlock Switches allow access to hazardous areas only when an appropriate key is inserted into the interlock. These stainless steel bolt interlocks provide a rugged, industrial grade method of helping prevent access through gates. With these bolt interlocks, there is no need to run power wires to the gate. These bolt interlocks are available in mechanical, electrical and solenoid switch types.
