Question: How do you install a 4-way switch?

Does it matter which wire goes where on a 4-way switch?

More videos on YouTube It doesnt matter which traveler wire goes on which bottom screw. Then connect the two travelers from the other 3-way switch to the top screws on the 4-way switch. Another key point is it doesnt matter which traveler wire you attach to which screw.

What is a 4-way installation?

Wiring a 4-way switch is simply adding a switch to an already existing 3-way switch circuit. This allows you to control a load from other locations in addition to the (2) locations that a 3-way circuit provides.

Where does the white wire go on a 4 way switch?

Attach the black and white/blue traveler wires entering the 4-way switch box to the in terminals, often the top terminals on the 4-way switch - black on the left top pole and white/blue on the right top pole. Some 4-way switches may have the in and out pairs opposite each other, rather than top and bottom.

What is the difference between a 3 way and 4 way switch?

A three-way switch has three terminals; a four-way has four. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances.

Are 3 way and 4 way switches the same?

A four-way switch is similar to a three-way, except it has four terminals (plus a ground terminal) and controls one fixture from three locations. This type of switch must be combined between two three-way switches to form a circuit.

Can you put a dimmer on a 4-way switch?

Correct, no 4 way dimmers. The 3 way must be at either end of the switch legs, whatever it takes. If the dimmer is desired in a location where only a 4 way switch makes sense, the only solution is to extend the power and double back the switch legs so that it becomes the end.

Can I use a 4 way switch in place of a 3 way?

Sure, a 4-way is essentially two 3-ways in one device. Usually a 4 way switch has 2 (IN) screws and 2 (OUT) screws. Using one of the (IN) terminals is the same as the common terminal on a 3 way. And using the (OUT) terminals is the same as the traveler terminals on a 3 way.
