RS PRO PCB Mount Toggle Switch On-Off-On SPDT 28 V DC 112 V AC Through Hole 401-670

RS PRO 401-670 PCB Mount Toggle Switch is a compact, single pole double throw (SPDT) switch engineered for versatile circuit control in electronic and industrial environments. Designed for On-Off-On actuation, this switch allows direct switching between two outputs, ideal for controlling operations or indicators in machinery, automation, and assembly lines.

This toggle switch features a robust chrome-plated brass actuator that delivers excellent resistance to corrosion and mechanical wear. The actuator locks firmly into position with a positive feel, preventing accidental switching. Silver contacts guarantee efficient current transfer, minimizing resistance and response delay in demanding applications.

The device is rated for 28 V DC and 112 V AC operation, with a contact current up to 5A. Its PCB mount and through-hole terminal configuration simplifies integration into electronic projects and commercial PCB layouts, ensuring a stable, soldered connection for long-term reliability. The actuator length of 10.41 mm allows for easy access and manual operation, while the construction is sealed with epoxy to protect against soldering-related contamination.

Engineered for industrial durability, the RS PRO 401-670 switch withstands a mechanical life of 40,000 cycles. Its operating temperature range from -30°C to 85°C makes it suitable for installation in harsh manufacturing, laboratory, and automation environments. Classified as RoHS compliant, the switch meets international lead-free standards for environmental safety.

Applications include electronics manufacturing, machine control panels, process automation, laboratory instrumentation, and commercial equipment. The combination of SPDT contact configuration, On-Off-On operation, and reliable through-hole PCB mounting makes this switch a preferred choice for engineers seeking precise, repeatable, and safe circuit switching solutions.

SPDT configuration enables switching between two separate outputs with a single actuator. Rated for both DC and AC operation, allowing flexible deployment across electronic and electrical systems. Corrosion-resistant brass actuator and high-quality silver contacts deliver stable, long-term performance.

Through-hole PCB terminals support secure, soldered mounting in assemblies and prototypes. Rugged construction and wide operating temperature range make it dependable in industrial and laboratory settings. 40,000 mechanical cycles specification ensures robust lifecycle under repetitive use.
