Allen-Bradley 440K-T11466 Tongue Switch, 500 VAC, 10 A

The Trojan family is a universal tongue operated (or key operated) safety interlock switch designed to fit at the leading edge of sliding, hinged or lift off guards. The dual key entry slots and rotatable head, movable only by releasing the cover screws, allow four actuator entry options. The Trojan contains all of the safety related functions i.e., forced guided contacts, tamper resistant mechanism allowing the machine to be safeguarded in compliance with the machine directive. Operation of the switch is achieved through the insertion of a specially-profiled stainless steel key that is permanently mounted to the leading edge of the guard door. The standard (not GD2) Trojan actuator includes a self-ejecting mechanism that prevents operation of the switch if the actuator is not mounted to the guard door (e.g., if the operator uses a spare key).
