Single Pole Double Throw Light Switch Wiring

Two lights between 3 way switches power via a light how to wire a 4 way light switch with power feed via the light switch.

Single pole double throw light switch wiring. Double throw switches can divert the flow of electricity from one set of screw terminals to another. It has four terminals. Single pole switches are the most common light switches in a home. These screw terminals are mounted on the side of the switch.

You can see above how a double pole single throw switch can be used to put a circuit in any of 1 of 2 modes. Single pole switch is referred as a single pole single throw switch. The difference between a single and double pole switch is that the latter controls two circuits at the same time. It can serve as an on off switch depending on how the circuit is wired.

Double pole single throw switch dpst circuit. They have two screw terminals plus a ground screw. A single pole double throw spdt switch is a switch that only has a single input and can connect to and switch between 2 outputs. Two for incoming hots and two for outgoing hots.

3 way switch single pole double throw or spdt browse lighting diagrams that use a 3 way switch. This means it has one input terminal and two output terminals. Single throw type switches designate an on or off type operation. The other terminal is for a second hot wire called a switch leg that runs only between the switch and the light fixture.

A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection. When the switch is connected one way for circuit a and circuit b the lamp and led will both be on. 4 way light switch with power feed via the light. One screw terminal is for the hot wire that feeds the switch from the power source.

A double pole switch can be used to control light and a fan or 2 lights on separate circuits. It is easy to wire a double pole switch to work as a single pole switch because only one side is used instead of both. Below is an example of a circuit which utilizes a double pole single throw switch. In other words it s like two simple switches controlled by a single actuator.
