Schneider Electric XCSL766B2 Pushbutton Switch

Schneider Electric Telemecanique XCSL766B2 is a key-locking safety interlock switch used to secure access to guarded areas of industrial equipment. As part of the XCSL family, the device combines an interlock mechanism with a keyed locking feature to prevent operation when a guard is open and to provide controlled release only when the appropriate key is used. This type of switch is commonly deployed on guard doors for presses, packaging lines, conveyors, and other automated machines where safeguarding personnel is critical. The XCSL766B2 model designation identifies a specific configuration within the XCSL safety interlock lineup, and the part is cited in Schneider Electric-related catalogs and distributor listings under Telemecanique Sensors for interlock, key-locking safety switches. Typical installations pair the interlock with a compatible safety relay or controller to enforce a safe-off condition when the barrier is open, ensuring that machine start-up is prevented until the door is closed and the key is secured in the locking mechanism. The product is designed for industrial environments and is compatible with standard control wiring used in safety circuits.
