Allen-Bradley TLS2-GD2 Safety Interlock Guard Switch This unit was pulled from a working system, and appears to be in very good working shape; however it is untested. The TLS-GD2 is a positive-mode, tongue-operated guard-locking interlock switch that locks a machine guard closed until power is isolated while the guard is open. The TLS-GD2 head has two entry slots and can be rotated to provide four actuator entry points. A blanking plug is provided to seal the unused slot. Power can only be restored through the guard after a signal is applied to the TLS-GD2 s internal solenoid to release the locking mechanism. Therefore, the TLS-GD2 is ideal for machines which do not stop immediately or where premature interruption of the machine could cause damage to tooling and components or cause an additional hazard.
