SAFETY SWITCHES
GKM Series
Global Miniature
Safety Key
Operated Switch
Used alone as Category 1 safety components or, in conjunction with other safety switches and our complete
range of safety relays, it is possible to construct comprehensive protection schemes with Category 2, 3 or 4
compliance.
The preleaded versions allow rapid fit, easy cable routing and function testing which cut costs dramatically
in OEM applications. Simple upgrade guarding solution for End User applications.
