  • thanks alot

  • i have a switch that has 4 prongs sticking out. Can i use this switch amd if so, how?

    Good video.

  • yes you can. A push button should have 4 prongs. 2 for normally open and 2 for normally closed. normally open means it is off until the push button is pressed. normally closed means the opposite. obviously you want the normally open; usually the 2 corresponding prongs for NO or NC are diagonally across from each other. You just have to find which ones are which. you can do this by hooking a visible light source up to it and see if it comes on when you push the push button.

    hope this helps
