Honeywell GKE Series - MICRO SWITCH Key-Actuated Safety Switches:

The Honeywell GKE Series key-operated safety interlocking limit switches are designed for machine guarding applications. The switches mount on the EN50047 mounting pattern of the 20 mm to 22mm mounting centers. The compact size is preferred where there is limited space on machinery. The double-insulated plastic housing and rugged stainless steel actuator key is a logical choice for demanding environments. The design of the switch allows the actuator key to be inserted from the top or side of the switch. As with the Honeywell safety limit switches, all normally closed contacts are positive opening.
