Frequently asked questions
How do I wire the micro-switch to a microcontroller?
Connect one micro-switch terminal to a GPIO pin and the other to GND, then enable the MCU's internal pull-up. Confirm the terminal arrangement with a multimeter in continuity mode, since the switch's contacts are the key part of the wiring.
Can I fit an LED inside the button?
Yes. The holder is designed to take an LED, so you can add a light to the button. Choose an LED whose body fits the holder and use a current-limiting resistor in its circuit.
