AE090 Kuongshun Set of 25 Tactile Push Button Switches 12x12mm 7.3mm height, 4-pin through-hole, normally-open momentary action. Includes 25 color-coded caps (5 colors × 5 pcs) in a re-sealable storage case — ideal for Arduino, breadboard, and PCB projects.

 

The Kuongshun AE090 is a set of 25 tactile push button switches in the popular 12×12mm footprint with 7.3mm actuator height and a 4-pin through-hole configuration. Tactile switches are the go-to momentary input component for any electronic project: when idle the circuit is normally open, and pressing the button briefly closes the contact — giving microcontrollers like Arduino or ESP32 a clean, debounce-friendly signal. The kit also ships with 25 color-coded caps (5 colors, 5 pcs each) and a re-sealable plastic storage case, making it a complete starter pack for makers, students, and engineers alike.

Key Features

  • Momentary normally-open action: Pins open at rest, closed only while pressed → safe, predictable digital input
  • 12×12mm standard footprint: Fits virtually any universal PCB or prototype board → drop-in compatible with most layouts
  • 7.3mm actuator height: Comfortable tactile travel above the PCB surface → easy to press, even in enclosures
  • 4-pin through-hole: Dual redundant contacts on each side → mechanically stable and reliable soldering
  • 25 color-coded caps included: 5 colors × 5 pcs → instant visual differentiation of button functions
  • High-precision mechanism: Long service life micro push-button design → consistent actuation force over many cycles
  • Re-sealable storage case: Rugged plastic case keeps components organized → no lost parts on the workbench

Pinout & Wiring

Pin PairSymbolDescription
1 – 2 (left side)AInternally connected pair — one side of the switch contact
3 – 4 (right side)BInternally connected pair — other side of the switch contact

Wiring note: Connect one pin from side A to your microcontroller GPIO (with an internal or external pull-up resistor) and one pin from side B to GND. The remaining pins on each side are electrically identical and can be left unconnected or used for mechanical stability on the PCB.

Typical Applications

  • Arduino / ESP32 input buttons: Add physical user input to your microcontroller project — menu navigation, reset triggers, mode selection
  • DIY keyboard & button pads: Build custom macro pads, game controllers, or instrument panels with color-coded caps for instant identification
  • Remote controls & household appliances: Replace or prototype control panels for home electronics
  • Educational & lab prototyping: Perfect for breadboard experiments and soldering practice — a staple component in every electronics lab
  • Robotics & wearables: Compact 12×12mm size fits tight enclosures; caps protect the actuator from accidental presses

FAQ

Q: Do I need external resistors to use these with Arduino?
A: Yes — connect the switch between GPIO and GND, and enable the Arduino's internal pull-up resistor (pinMode(pin, INPUT_PULLUP)). This ensures a clean HIGH/LOW reading without floating pins.

Q: Are the caps compatible with other 12×12mm tactile switches?
A: The included caps are designed for the 12×12mm actuator size. They will fit any tactile switch with the same footprint and a compatible actuator stem diameter.

Package Contents: 25 × Tactile Push Button Switch (12×12mm, 7.3mm, 4-pin) + 25 × Color caps (5 colors × 5 pcs) + 1 × Re-sealable plastic storage case.

⚠ Note: These are through-hole components designed for PCB or breadboard use. Ensure your board's hole pitch matches the 12×12mm footprint before ordering.
