GK Series

Heavy duty construction for harsh industrial environments

Designed with a wide key entry tolerance, to accommodate drift in door alignment over the life of the machine,

Compliance with the relevant European directives is assured with this design. Each switch is available with either a straight or a 90° key.

Contact blocks have screw terminals enabling use of spade wiring terminals, complying with global safety requirements.

Galvanically isolated contacts permit wiring normally closed and normally open contacts to different loads and polarities.

Forced disconnect mechanism on normally closed contacts conforms to IEC 947-5-1.
