SCHNEIDER ELECTRIC Industrial Push Button Switch, Momentary, SPST-NO, Green

The SCHNEIDER ELECTRIC XB4BA31 is a robust, momentary-action industrial push button switch designed for demanding commercial and industrial applications. Featuring a single-pole, single-throw, normally open (SPST-NO) contact configuration, this switch is engineered for high reliability and long service life.

Constructed with a durable chromium-plated metal bezel and a Zamak alloy fixing collar, the switch offers excellent resistance to corrosion and mechanical stress. The actuator is a spring-return, green flush button, providing a clean, unmarked appearance suitable for modern control panels. Electrical connections are made via secure screw clamp terminals, ensuring a stable and vibration-resistant contact.

The heart of the switch is its slow-break silver-nickel (Ag/Ni) alloy contacts, which are designed to minimise arcing and ensure consistent performance over millions of operations. With a mechanical durability rating of 5,000,000 cycles, this component is built for endurance in high-frequency use environments.
