AJMRTC tactile push button kit contains 25 pieces of 12×12×7.3mm CLT momentary tact switches paired with 25 multi-color key caps. The 4-pin through-hole switches deliver crisp tactile feedback and reliable momentary on-off performance, ideal for building custom keypads, control panels and electronic prototypes. Comes with five different colored key caps to visually separate multiple button functions, which simplifies debugging and operation. Switches are simple to solder onto PCB boards or breadboards, perfect for Arduino, Raspberry Pi DIY projects, circuit testing, keyboard modification and electronic equipment maintenance. All components are packed in a transparent storage box to keep parts sorted and prevent loss.
