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 mecha-
nism. The switch is used on machinery where instant stop and access to the machin-
ery 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 inter-
rupted).
The switch incorporates a manual override feature which allows removal of the key
for emergency access.
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.
