SAFETY SWITCHES
GK Series
Dual Entry Key
Operated Safety
Interlock Switch
The GK Series is designed specifically for use on machines where key removal brings the machine to an
immediate safe condition. It provides enhanced operator safety when added to hinged or sliding guard
doors, screens and protective covers on enclosures. The GK Series is especially well suited for large door
applications, typically in the automotive plant floor environment. Its heavy duty construction withstands
harsh industrial environments where rugged, long-term durability is required.
Nearly 1000 options are available in a simple to understand part number tree.
A safety lockout device is also available for use with the GK Series. The lockout device (GKZL2) is specifically
designed to prevent a key from being inserted either manually, or by the access door being closed while
maintenance personnel are working on the machine. When inserted, the lockout device can accommodate
up to four padlocks to prevent unauthorised removal of the device.
