Seco-Larm SS-032Q/RD Red Push Button, Momentary SPST Pushbutton, Fits 1/2" (13mm) Hole, Rated 1 Amp at 12VDC, N.O. Switch

so this is a momentary push-button switch the interesting thing about this as it can work and normally open or normally closed I'm gonna show how that works so I guess the switch is off and then once I press the button turns on that means it's normally open and also with pressing it and then the motor turns on then moving my finger it turns off automatically that's called the momentary momentary push-button switch and this is normally open so I must show normally closed so what I'm doing is I am switching the wires from this side from this side to this side so with this switch if you need to use normally open and normally closed on two different circuits you can do that so right now it's on normally closed but by powers off my power supply so that's why this hurry on but power all my power supply to fan tip Bob right I push the button turns off so this is normally closed
