Schmersal TZFWS24VDC Safety Interlock Switch With Keys

Schmersal TZFWS24VDC Safety Interlock Switch With Keys is a solenoid‑operated guard‑locking interlock that secures a machine door when the guard is closed and unlocks when energized. It operates on 24 V DC, features a normally open contact, and uses a thermoplastic enclosure with a magnet rated for 100% duty cycle and up to 1,000,000 switching cycles. The package includes a triangular manual release key and the necessary mounting hardware, enabling immediate release and reliable re‑locking of the guard. This interlock is intended for safeguarding equipment by ensuring the guard cannot be opened while the protected process is energized or unsafe.
