Frequently asked questions
Is this switch SMD or through-hole?
The title says SMD/Patch, while the description mentions through-hole applications. Check the physical pins and compare them with your PCB footprint before ordering or soldering.
How do I wire a 4-pin tact switch?
The two pins on each side are internally connected, and pressing the button bridges the two sides. Connect one side to a GPIO pin and the other side to GND, then use a pull-up resistor (internal or external) so the input reads high when released.
