Schmersal 101022605 Keyed Safety Interlock Switch

Schmersal 101022605 is a keyed safety interlock switch (TZFWS24VDC) intended for safeguarding machine guards and access doors in industrial equipment. The TZFWS24VDC designation indicates a 24V DC coil, aligning with common control-circuit practices for safety interlocks. Identified by the part number 101022605, this configuration belongs to Schmersal’s TZFWS family of keyed interlocks. In use, the device is mounted on a door or guard and operated by a keyed actuator to provide controlled access while the safety circuit is engaged, helping prevent entry to a hazardous area while the machine is powered or in an unsafe state. This type of interlock is typically integrated into safety logic alongside other protective devices to maintain secure guarding during operation and service. Designed for reliability in industrial environments, the keyed mechanism supports controlled access and reduces the risk of unintended reentry, enabling safe maintenance and routine operation within standardized safety practices.
