SCHURTER SMS Tactile Switch SMD SPST 180gf 42V DC 50mA

The SCHURTER SMS Tactile Switch is a miniature, surface-mount pushbutton switch designed for automatic assembly. With a low profile of just 4.55 to 4.95mm, this switch features a large, flat top surface and an equally flat, parallel bottom surface, making it ideal for pick-and-place machinery and IR-reflow SMD soldering. Its compact 11.4mm x 11.4mm footprint saves valuable PCB space while maintaining a reliable, momentary SPST contact configuration.

The switch delivers a very good tactile response with an actuation force of approximately 2N (180gf), providing clear feedback for every press. Rated for 50mA at 42V DC, it is suitable for low-power control and signal applications. The IP40 protection rating ensures resistance to tools and wires larger than 1mm, while the non-illuminated, top-actuated round button design offers straightforward integration into various electronic devices.
