The ST14 Series is designed for use with movable machine guards which must be closed for operator safety. Their twopiece, tamper-resistant design, and positive-opening NC contacts, provide a significantly higher level of safety than conventional, spring-driven switches whose contacts can weld or stick shut. Their NEMA 4 (IP67) rating make them ideal for interlocking safety guards in hostile environments. Their compact design allows use in applications where space is severely limited. -Contacts: 1 NO & 1 NC; 2NC
