The Tactile Momentary Push Button Switch – Pack of 20 is a compact and reliable micro push-to-on switch designed for a wide range of electronics, robotics, embedded systems, and DIY projects. These tactile switches are momentary contact devices — they only stay ON while pressed and return to OFF when released — making them ideal for responsive user inputs such as reset buttons, menu selection, mode toggles, and control triggers.

Each switch in this pack features a tactile feedback action, giving a subtle physical click when pressed, which helps with accurate actuation and enhances usability in interactive designs. The SPST (Single Pole Single Throw) contact configuration makes wiring simple and intuitive, and the standard through-hole PCB mounting ensures solid, stable installation on custom PCBs, prototyping boards, or controller shields.

Rated for typical low-power use, these buttons are well suited for interfacing with Arduino, Raspberry Pi (via pull-ups), AVR, PIC, ARM, 8051 and other microcontroller platforms in robotics and automation circuits. Whether you’re building robot control panels, remote interfaces, instrument keypads, educational electronics kits, or arcade button layouts, these tactile switches offer versatility and reliability.

Supplied as a pack of 20 buttons, this set is perfect for classroom labs, workshop benches, production prototypes, and bulk build-outs. Compact yet rugged, they are a fundamental component for any maker, student, or engineer developing interactive electronic systems.
