Multicomp Pro Momentary Push Button Switch, SPST-NO, R/A PCB Mount

The Multicomp Pro Push Button Switch is a sealed, sub-miniature momentary action switch designed for reliable performance in demanding industrial applications. Constructed with a durable stainless steel housing and a resilient diallyl phthalate (DAP) casing, it offers excellent resistance to environmental factors and mechanical stress. The switch features high-quality silver-plated copper alloy contacts, ensuring low contact resistance and reliable electrical performance over an extended lifespan.

This switch is engineered for a mechanical life of 50,000 make-and-break cycles, providing dependable operation for frequent use. It operates effectively across a wide temperature range of -30 to 85°C, making it suitable for use in challenging conditions where temperature stability is critical. Its compact dimensions allow for efficient use of space on printed circuit boards (PCBs).

As a through-hole mounted component with PC pin terminals, it is easy to integrate into electronic assemblies using standard soldering techniques. The pushbutton actuator features a black plunger style, providing a clear, tactile interface. The switch configuration is single-pole, single-throw, normally open (SPST-NO), with a momentary off-(on) operation, meaning it only makes contact while the button is actively pressed.

With a maximum rating of 3A at 120V AC or 3A at 28V DC, this switch is versatile for a variety of low to medium power control circuits. Its robust construction and sealed design contribute to its reliability, making it a trusted component for engineers and technicians seeking a high-performance tactile switch solution.
