A four-way switch is a double pole light switch. One switch controls two circuits. This can be used to control a circuit from multiple locations in a series of switches.
Four-way switches are used to control lighting. Four-way switches and three-way switches are used. The four-way switch has four terminals that can be used for two sets of positions. One of the positions is the terminal set.
A double-pole switch allows you to control two circuits at the same time, while a three-way switch allows you to control one circuit from two different locations. A double-pole three-way switch can integrate these functions.
A three-way switch has three terminals. The light can be controlled from two or three locations, such as at the top and bottom of a stairwell, at the end of a hallway or in a large room with multiple entrances.
The white wire is from the power source. The black wire should go to the first switch. The white wire will be connected to the dark colored screw at the switch.
The standard single-pole switch only controls a light from one location. The four-way switch is used in conjunction with two three-way switches to control lighting from more than one location.
One of the simplest types of switches is single-pole. They typically have on/off markings on a switch to indicate whether power is flowing to the device.
Three pole or three-way switches are used to control lights and fixture from multiple locations, such as the top and bottom of a flight of stairs When installed, single pole and three pole switches look the same, but are used in different ways.
A pole is the number of circuits that a switch controls. A double pole switch can control two wires at the same time, while a single pole switch can switch one wire.
