How To Wire A 4 Way Switch With Power At Switch

This allows you to control a load from other locations in addition to the 2 locations that a 3 way circuit provides.

How to wire a 4 way switch with power at switch. 4 way switches can be quickly identified by the 4 screw terminals in addition to the green gnd screw terminal. How to wire a 4 way switch. Power coming into switch first. The switches are powered from the light fixture.

When the switch is operated current will either travel straight through or crisscross. 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. Two of the terminals are brass and labeled input the other two are black and labeled output. Study the 4 way switch and the manufacturer s directions.

Four way switches have four terminals. Two terminal poles are labeled in and two are labeled out pairs of wires called travelers will connect to each side. Power coming into the light fixture first. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wirenut.

Power coming into switch first. Sometimes the switch wiring connection diagram is printed on the inside of the 4 way switch packaging box see example below. When wiring a 4 way switch circuit as shown below. This circuit diagram shows wiring for a 4 way circuit with the power source at the light fixture and the switches following.

The hot connects to the common on that switch and the neutral is spliced through all the switch boxes to the neutral terminal of the light. A 4 way switch has 4 terminals or poles. Bare or green ground wires are spliced together with a pigtail or two and then connected to the metal switch box with a 10 32 machine screw and to the green screw on the 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.

Power coming into the light fixture first. This 4 way switch diagram 2 shows the power source starting at the fixture. This type of switch works in combination with two three way switches to control electricity to lights from three or more locations. A two wire cable c2 is run from the light to the first switch sw1 and a 3 wire cable runs between all the switches.

This 4 way switch diagram 1 shows the power source starting at the left 3 way switch. In this 4 way light circuit the power source is via the first switch sw1. Wiring a 4 way switch is simply adding a switch to an already existing 3 way switch circuit. There are two basic setups for wiring a 4 way switch.

They support hot conductors traveller wires which receive and transfer electricity from each of the three way switches. It is very important to pay attention to these as shown in the 4 way switch diagram.
