How to Wire a Micro Switch
|
How to Wire a Micro Switch Switches are used to complete electrical circuits. When a switch is flipped an internal contact connects and allows electricity to pass through the circuit. Like some toggle switches, a micro switch can be used to perform two different actions. One contact can control left movement and the other right movement. With a micro switch the separate movements can be made very quickly. With a micro switch there is no neutral or off position. One circuit is by default constantly on until contact is made in the switch to engage the other position. If the second or nonconstant leg is not wired then the micro switch will act as a brake or pause to the action. 1 Cut four pieces of wire 12 inches long. Strip the plastic coating off the wire 1/2 inch from each tip on the wires. 2 Attach one wire to the positive terminal on the light socket. Attach the other end to the positive terminal on the battery. 3 Attach a wire to the negative terminal on the light socket. Attach the other end to the NO, or normally open, terminal. 4 Attach a wire to the common terminal of the micro switch. Attach the other end of the wire to the negative terminal on the battery. 5 Turn on the light by pressing the button. As long as you hold the button the light will stay on. |
