Pack of 20 4PIN DIP TACT push-button key power tactile switches — 12 x 12 x 9 mm, light-touch operation Key benefits Ready-to-use bulk supply: 20 identical switches for repairs, production runs, or spares so you don’t run out mid-project. Reliable tactile feedback: positive "click" feel helps prevent missed activations and improves user confidence for power and key functions. Low operating force: light-touch action reduces finger fatigue for frequent use and gives a smooth user experience. Space-efficient footprint: compact 12 x 12 x 9 mm size fits tight layouts while providing a clearly defined key surface. Standard 4PIN DIP compatibility: designed for common 4-pin DIP through-hole PCB footprints, simplifying replacement and prototyping. What this switch does and how it helps Function: single tactile push-button intended for power or key input roles where a defined, repeatable press is required. Compatibility: fits PCBs and assemblies that accept a 4PIN DIP tactile switch in a 12 x 12 x 9 mm form factor. Ideal when you need a direct, drop-in replacement or a standard tactile input for a custom board. Performance: light-touch operation and a consistent tactile feel deliver predictable user interaction across multiple switches and units. Practical applications Electronics repair and refurbishment: replace worn or broken power/key switches in consumer electronics, audio equipment, or small appliances that use a 12 x 12 x 9 mm 4-pin tactile switch. Prototyping and DIY projects: add reliable, low-force tactile buttons to microcontroller projects (Arduino, Raspberry Pi add-ons) and custom control boards that use 4PIN DIP footprints. Control panels and instruments: provide consistent tactile power/key inputs for test equipment, industrial panels, and other enclosures where compact, repeatable switches are required. Notes for installers Ensure the PCB or panel accepts a 12 x 12 x 9 mm 4PIN DIP tactile switch footprint before installation. Through-hole soldering to the 4 pins is the standard mounting method for these switches.
