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.
Low energy basic switches are rated as follows:
Operating Voltage U
1 Vdc to 60 Vdc or 1 Vac to 125 Vac
e
Operating Current I
1 mA to 50 mA
