Pushbutton 6mm Reference
Compact 6mm tactile pushbutton (SPST-NO), same pin layout and behaviour as the standard Pushbutton, in a smaller footprint.
Pin names
The button has four pins arranged in two pairs. Pins on the same side (1.l/2.l or
1.r/2.r) are always connected to each other internally. Pressing the button bridges the
left pair to the right pair.
| Pin ID | Label | Description |
|---|---|---|
1.l | 1 Left | Terminal 1 — left side |
2.l | 2 Left | Terminal 2 — left side (internally connected to 1.l) |
1.r | 1 Right | Terminal 1 — right side |
2.r | 2 Right | Terminal 2 — right side (internally connected to 1.r) |
For most circuits you only need one pin from each side — use 1.l and 2.l (as in all
CNAP templates), or 1.r and 2.r.
Attributes
| Name | Description | Default |
|---|---|---|
| color | Button cap colour: "green", "red", "blue", "yellow", "white", "black" | "green" |
Usage
Connect one pin to a GPIO, the other to GND. Enable INPUT_PULLUP in setup() — the pin
reads HIGH when released, LOW when pressed. No external resistor needed.
const int BTN = 2;
void setup() {
pinMode(BTN, INPUT_PULLUP);
Serial.begin(9600);
Serial.println("Press the button!");
}
void loop() {
if (digitalRead(BTN) == LOW) {
Serial.println("Button pressed!");
delay(200); // simple debounce
}
}Examples
| Description | Attrs |
|---|---|
| Default green cap | {} |
| Red cap | { "color": "red" } |
| Blue cap | { "color": "blue" } |
