How To Wire A 4 Way Switch With Power At Switch

Power coming into switch first.

How to wire a 4 way switch with power at switch. They support hot conductors traveller wires which receive and transfer electricity from each of the three way switches. Power coming into switch first. It is very important to pay attention to these as shown in the 4 way switch diagram. Study the 4 way switch and the manufacturer s directions.

Sometimes the switch wiring connection diagram is printed on the inside of the 4 way switch packaging box see example below. Two of the terminals are brass and labeled input the other two are black and labeled output. Power coming into the light fixture first. This 4 way switch diagram 2 shows the power source starting at the fixture.

This 4 way switch diagram 1 shows the power source starting at the left 3 way switch. In the picture given above a 14 2 cable 2 wires with the ground is being used and it is running from the light fixtures to the three way switch. 4 way switches can be quickly identified by the 4 screw terminals in addition to the green gnd screw terminal.

Two terminal poles are labeled in and two are labeled out pairs of wires called travelers will connect to each side. How to wire a 4 way switch. This allows you to control a load from other locations in addition to the 2 locations that a 3 way circuit provides. When the switch is operated current will either travel straight through or crisscross.

This circuit diagram shows wiring for a 4 way circuit with the power source at the light fixture and the switches following. Power coming into the light fixture first. This type of switch works in combination with two three way switches to control electricity to lights from three or more locations. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wirenut.
