SAFETY SWITCHES
GKL/GKR Series
Dual Entry Solenoid
Key Operated Safety
Interlock Switch
The GKR (head to the right) and GKL (head to the left) products offer the user an unrivalled range of standard
options.
The GKR/GKL product is a key actuated device incorporating a key trapping mechanism. The switch is used
on machinery where instant stop and access to the machinery is either impossible (due to the momentum of
the machine) or impractical (due to tool or machine damage or scrapped product if the current machine
cycle is interrupted).
The switch incorporates an optional manual override feature which allows removal of the key for emergency
access.
Over 1000 options are available in a simple to understand part number tree.
A safety lockout device is also available for use with the GKR/GKL 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.
