Saia-Burgess High-Performance SPDT Micro Switch 250VAC 15A IP54 Poland 4BR

Saia-Burgess 4BR Micro Switch is a high-performance single pole double throw (SPDT) snap action switch manufactured in Poland. Designed for reliable and precise switching, this micro switch supports a voltage rating of 250VAC and a current rating of 15A, making it suitable for electrical and automation applications.

The device operates with a simulated plunger lever actuator requiring a 7.2N force to energize the internal spring mechanism, enabling fast and accurate switching action. It features a compact design with screw terminals for easy and secure wiring connections.

The micro switch’s robust construction includes zinc alloy contact material and a snap-on insulation terminal to ensure long-lasting durability. It is designed for through-hole mounting and is sealed to an IP54 rating, providing basic protection against dust and water, with pre-wired variants also available with IP67 sealing for enhanced environmental resistance.

Supporting an operating temperature range of -40°C to +85°C and a mechanical operating life cycle of up to 10 million operations, the Saia-Burgess 4BR Micro Switch is highly reliable for continuous industrial and automotive use.

The switch offers compactness with precise and repeatable snap action performance. Its metal housed roller plunger design ensures mechanical robustness. The switch provides flexibility with normally open or normally closed contacts.

Applications include automotive systems and various electronic equipment requiring dependable switching. Sealing ratings IP54 (standard) and IP67 (pre-wired models) protect the switch from harsh environmental conditions.

Installation is simplified with through-hole mounting and screw terminal designs. Operating temperature from -40°C to +85°C allows use in diverse climates and conditions.

This Saia-Burgess micro switch serves industrial, automotive, and electronic automation sectors requiring compact, durable, and high-cycle reliable switches. It is part of a trusted legacy of snap action microswitches widely used in manufacturing and control systems.
