The RS PRO single pole single throw (SPST) momentary push-button switch is a straightforward mechanism for controlling an action in a machine or other electrical process. You'll find these kinds of switches in home, office and industrial settings. It's well-suited to a range of applications including medical equipment and telecommunications.

With a panel cutout diameter of 4.95 mm, this is classified as a subminiature switch. It features a solder terminal for a quick connection. The switch has a panel-mounted design that means it can be secured to equipment, external cases or enclosures. It has a contact AC voltage rating of 120 V, 250 V and contact DC voltage rating of 28 V.

Like all of our RS PRO range, it's been tested by engineers for durability and consistency. There's a black actuator, made from hardwearing thermoplastic polyester. It comes with gold- or silver-plated contacts for effective conductivity.
