Test Two Separate Wall Switches To Same Light

Wiring two switches for two lights.

Test two separate wall switches to same light.

A hot wire red or black comes out of the wall and into one switch then out of that switch and into the other one. Connect black fan wire to the black ceiling wire. Some gang boxes are in locations that do not allow the box to be expanded to add a separate light switch. One source is spliced to each switch with a pigtail to power the two lights.

It isn t unusual to wire two or more light and switch combinations from the same power source in fact it s common practice. The source is at the switch box and a 2 wire cable is run to each light. Wiring two switches to one light fixture adds convenience to any room with two entryways. Here two switches are wired in the same box to control two separate lights.

There are also four way five way and a gazillion way circuits. To do this method the wire from your wall circuit to your light has to have 3 wires. Also known as three way switching the job calls for a pair of special three way switches and an appropriate length of 14 3 conductor cable to join the switches together. How to wire two separate switches lights using the same power source.

Stairwells hallways and large rooms with multiple access are all candidates for 3 way circuits. An existing wall dimmer switch must be replaced with a single on off wall switch before installing a hunter fan to ensure consistent power flow from the switch to the fan. My question is how do i wire this up so that either switch will control the light without having to touch the other switch. This is common with some older boxes when you have two single switches hooked up instead of one double switch.

This method allows you to operate the fan and light power separately. I know this can be done but i don t have a clue how to connect the switches to the fixture. Your power supply line the black wire should be feeding both switches and those switches power the fan black or the light blue. You can wire two single pole light switches in the same gang box using a device that combines two separate single pole light switches into one device using the original single switch space.

As the diagram at electrical 101 shows the line cable is all you need to supply power to a pair of switches in a single electrical box. Once you pull the 14 3 cable and the circuit power source wires from the switch boxes. A 3 way circuit is a lighting circuit that allows one light fixture to be controlled by two wall switches in different locations. It may in some cases even return to the wall from the second switch.
