Global Miniature Key Interlock Safety Switch
MICRO SWITCH™ GKM Series
DESCRIPTION
Honeywell Sensing and Control (S&C) offers safety switches to
meet your needs. Designed with OEMs in mind, we offer safety
switches in every size. The MICRO SWITCH™ GKM Series is
our miniature product line offering one of the smallest key-op
switches available. GKM has daisy-chain capability to reduce
installation and down time. Pre-leaded versions allow for rapid
fit, easy cable routing and function testing, potentially
cutting costs dramatically in OEM applications. Per safety code
EN 60954-1, components used alone comply as a Category 1.
By using components in conjunction with other safety switches
and modules, it is possible to construct a comprehensive protec-
tion schemes with Category 2, 3, or 4 compliance. Simple up-
grade guarding solutions are available for end-user applications.
