How to replace a single pole switch.

This is a fairly simple thing to do with only a few things to keep in mind. 1) Turn the power off to the circuit. 2) Double check that the power is off. 3) Remove cover plate. 4) Remove existing switch from the box while keeping the wires attached. 5) If it is a single pole switch you should have 3 wires connected to it, the feed, the switch leg and the ground. 6) Remove wires from existing switch and connect them to the new switch. 7) Install the new switch back into the box. 8) Replace the cover plate. 9) Turn the power back on. 10) Test your work.

Installing a new light and switch.

1) Determine the current for the circuit, that will determine what size cable you will use. 2) Run your feed cable from the electrical panel to your switch location. 3) Run your switch cable from the switch location to the light fixtures or fixtures. 4) Install an electrical box at the switch location and at every light fixture location. Make sure the box is rated for the weight of the light fixture. If you are installing a ceiling fan you will need a fan rated box. 5) Install your light fixtures. 6) Make your connections to the switch. Splice the white or neutral wires together. Connect the black wires to the switch terminals. Connect your ground to the switch ground terminal and the box if it is metal.

7) Install the switch into the box. 8) Install your cover plate. 9) Connect your feed cable in your main electrical panel to the proper size circuit breaker, and ground/ neutral bar. 10) Test your work.

  This video show the steps for wiring a switch.

  A single-pole switch is used to control lights from only one location. The switch has two screw terminals on the body of the switch. Most switches will also have a green grounding screw. A single-pole switch will have ON and OFF marked on the lever.

  A switch is just a break in the hot wire controlling a light. Both of the wires are HOT and should be black. If there are neutral wires in the box, they are not connected to the switch. They should be tied together with a wire nut. Always turn off the breaker or remove the fuse to the switch before wiring a switch.

Wiring a Single Pole Switch.2 Practical

• You can not play this video with this device.

  A single pole switch is used when one switch operates a light. The single pole switch will have 2 screw terminals and a ground screw.

  The switch will be marked with on and off on the lever.

  A switch is just a break in the hot, so you can connect the wires to either screw terminal
