🔘 4-Button PCB Module — 6 × 6 × 4.3 mm Tactile Switches
A ready-made four-button breakout on a green PCB, built around four 6 × 6 × 4.3 mm four-pin tactile switches. Each button has its own signal pin and they share a common ground, so four inputs need only five header pins.
✨ Key Features
- Four tactile push buttons, labelled K1–K4
- Common ground design — one ground pin for all four switches
- 2.54 mm header footprint, breadboard friendly
- Mounting holes at both ends for screws or standoffs
- Switches are the common 6 × 6 × 4.3 mm 4-pin type
- Silkscreen labels S1–S4 and C1–C4 for easy wiring reference
🔬 Specifications

🧰 Perfect for
• Menu and control panels
- Arduino, ESP32 and Raspberry Pi input
- Keypads, game controllers and MIDI boxes
• Testing and prototyping multi-button logic
• Machine and robot control
Tip: enable the internal pull-up resistors on your microcontroller and wire each button between its signal pin and GND.
