Honeywell’s GKM series global miniature safety key interlock switch is designed for use on machinery where key removal brings the machine to an immediate safe condition. The GKM series provides enhanced operator safety when added to hinged or sliding guard doors, screens and protective covers on enclosures.

The Honeywell MICRO SWITCH™ GKME series of dual connection safety switches is an extension of the GKM series. These new safety switches include two pre-assembled connectors that allow daisy-chain connections to be made from switch to switch and this can reduce wiring time up to fifty percent in some installations.

The GKME is designed to provide maximum machine safety and the removal of any switch indicates that a door is open and breaks the electrical safety chain.  The design also simplifies both planned and unplanned maintenance because modules can be easily removed and replaced.
