The Rockwell/Allen-Bradley TLS-GD2 is a tongue-operated guard locking interlock switch designed to prevent access to hazardous machinery until power isolation is confirmed. This positive-mode safety device maintains guard integrity during equipment operation and delayed-stop scenarios. The TLS-GD2 is available in power-to-lock and power-to-release configurations, with maximum holding force of 2000 N and peak force of 2600 N using steel bolts.
