The M-BS Trapped Key Bolt Interlock works on the principle that when the key is not present, the bolt is extended in the lock position with the guard closed. To unlock the M-BS Trapped Key Interlock, the key must be removed from the isolation switch device and/or the key exchange system and inserted into the trapped key interlock. Turning the key will re-tract the bolt, opening the guard and trapping the key in place.
Only when the guard is closed and the bolt is extended, can the key be released and placed back in the Isolator Switch or Key Exchange System. Power can then be re-applied to the guarded area.
It is important that when the bolt is retracted, it is held captive until the guard is closed. If you can extend the bolt whilst the guard is open, you are at risk of serious harm.
Skorpion Trapped Key Interlocks are manufactured in either mirror polished die cast or 316 stainless steel. The internal mechanisms are constructed using stainless steel, ensuring long term reliability even in harsh environments.
