Trapped Key Spring Handle Interlock with Single Key (M-HT)

The M-HT Trapped Key Interlock is a safety mechanism that operates using a spring-loaded handle lock mechanism. This locking mechanism is activated when the key is removed, securing the hazardous area. Access to the hazardous area is granted by inserting and turning the appropriate key to unlock the handle. To ensure long-term reliability, there is an anti-tamper cam system built into the M-HT interlock.
