Momentary 4-pin tactile push button switches in a 6×6×4.3mm package. Normally open, fits standard 6×6mm PCB footprints, easy to hand-solder. A staple component for Arduino prototyping, custom control panels, and PCB builds. Pack of 10.
Specifications
| Operation Mode | Momentary (normally open) |
| Pin Count | 4-pin (2 pairs of internally connected contacts) |
| Dimensions | 6 × 6 × 4.3mm |
| Mounting Type | SMT / Through-hole compatible |
| Pack Quantity | 10 switches per pack |
Pin Configuration
| Pins 1 & 2 (one side) | Internally connected — use either or both as one terminal |
| Pins 3 & 4 (other side) | Internally connected — use either or both as other terminal |
These are simple 2-terminal switches with 4 pins for PCB stability — pins 1 & 2 are the same node, and pins 3 & 4 are the same node. When pressed, pins 1/2 connect to pins 3/4. In a circuit: connect one side to your signal/power and the other side to ground or your input pin.
What's Included
| 10 × | 6×6×4.3mm tactile momentary push button switches |

General purpose momentary switching in DIY electronics
Common Questions
Do I need to use all 4 pins?
No — pins 1 & 2 are the same node, and pins 3 & 4 are the same node. You only need one wire on each side. The extra pins are for PCB mechanical stability, not extra circuits. For a breadboard, just use pins 1 and 3 (diagonally opposite).
Do I need a pull-up or pull-down resistor?
Yes — when used as a digital input on Arduino, connect one side to GND and the other to your input pin, then enable the internal pull-up in your code with
pinMode(PIN, INPUT_PULLUP). The pin reads HIGH when open, LOW when pressed.Please note: Normally open (NO) — contact closes when pressed. Fits standard 6×6mm PCB footprints. Pack of 10.
