Key interlocks

Key interlocks are said to provide a robust, fool-proof method of safe access to electrical switchgear and guarded machinery by ensuring that access guards remain locked until power has been isolated. The action of isolating power releases a key from a control switch when can be used to unlock and open a safety gate. 

This range of interlock devices can safe guard multi-worker access and prevent accidental lock-in. The products include key switch interlocks, exchange boxes, timer delay interlocks and door access interlocks.
