1 AUX.SWITCH C/O CONTACT OF/SDE/SDVNS80

1 AUX.SWITCH C/O CONTACT OF/SDE/SDVNS80 is a compact auxiliary switch built to add reliable signaling and interlock capability to industrial control panels and machinery. Featuring a changeover (C/O) contact, this unit provides a single common contact with both normally open and normally closed outputs, enabling flexible wiring and precise control logic without adding extra components.

With its SPDT configuration, you can route a single input to two separate circuits depending on the switch position. Use it to feed a PLC or safety controller, indicate machine status, or trigger interlocks when a door, guard, or access panel is opened or closed. The SDVNS80 variant integrates seamlessly with standard control gear, minimizing wiring complexity while maximizing signaling clarity.

• Changeover contact (C/O) for versatile signaling and interlock functionality
• Single auxiliary switch providing SPDT outputs for NO and NC paths
• Ideal for PLC input signaling, status indication, door interlocks, and interlock circuits
• Compact footprint designed for crowded control panels and switchgear assemblies
• Model-specific compatibility with OF/SDE/SDVNS80 series components

Wiring and integration tips: Use a common terminal as the reference point, connect normally open to NO line and normally closed to NC line. The changeover contact will switch between these outputs as the auxiliary switch actuates, enabling real-time signaling and control without cross-wiring. When selecting conductors, match the control voltage and current ratings to your system requirements and follow your panel’s electrical standards.

Who is this for? Engineers and technicians building automation solutions, machine builders needing reliable signal feedback, and maintenance teams implementing safety interlocks in conveyors, packaging lines, or processing equipment. If you’re upgrading legacy panels or designing a compact control cabinet, this auxiliary switch offers a clean, dependable way to integrate essential signaling with minimal space.
