Trapped Key Switch with Electronic Timed-delay

Our 440T Electronic Timed-delay Unit Trapped Key Interlock Switches are used in applications that require an elapsed time to occur before allowing access to a hazardous area. This interlock switch uses a Guardmaster® SI safety relay in combination with a Guardmaster EMD safety relay to execute the timing sequence. Turning a nonremovable key initiates the timer. When the EMD times out, its output energizes an internal solenoid, which then allows the removal of either one or two trapped keys.
