Frequently asked questions
Which terminal is NO and which is NC?
The listing does not specify the terminal layout. Use a multimeter in continuity mode with the lever released and pressed to identify the common, normally open and normally closed terminals before wiring.
How do I connect it to a microcontroller?
Connect the common terminal to GND and the normally open terminal to the input pin, then enable a pull-up on that pin. The input reads LOW when the switch is pressed.
