The NSI 76035PS is a durable, momentary Push‑OFF SPST pushbutton switch designed for dependable interruption of electrical circuits in a wide range of commercial, industrial, and residential applications. Featuring a bright red actuator for high visibility and a rugged screw‑mount design, this switch excels in scenarios where a fast, reliable momentary disconnect is required—such as emergency shut‑offs, equipment stop circuits, testing environments, and low‑voltage control applications.

This switch features a Normally‑Closed behavior in practical application context, meaning the circuit remains ON until the button is pressed, at which point the circuit opens momentarily. With its secure screw‑terminal connections, compact size, and suitability for temperatures up to 75°C, the 76035PS is engineered to withstand demanding conditions while maintaining ease of installation and consistent performance.
