Difference Between Single And Double Pole Light Switch

A double pole switch is what you need to control a 240 volt device because 240 volt circuits have two hot wires.

Difference between single and double pole light switch.

Because a single pole switch controls a single fixture it has two fixed positions. Provide 120 volts 15 20 amps and have one hot wire and one neutral wire. A four way has four. The main difference between a single pole switch and a double pole switch is related to the number of terminals they have and the number of circuits they control.

Two for incoming hots and two for outgoing hots. A switch is said to be open when there is no current flow between two terminals and is closed when the current flows from one terminal to the other. Single pole switch is referred as a single pole single throw switch. What is a single pole switch.

Like the single pole switch a double pole switch has on off markings and controls a device or equipment from one location. Well single pole breakers and double pole breakers differ in the voltage and amperage they provide as well as how they are wired.

In typical home wiring the hot wire from the electrical supply connects to one terminal and the hot wire to the fixture connects to the other. Let us show you the difference. It is commonly used in on off applications such as switches for light. It is a switch that provides a secure connection or disconnection over two terminals.

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. This allows the user to connect it to two pairs of hot wires from a 240 volt circuit. The difference between a single and double pole switch is that the latter controls two circuits at the same time. The single pole switch is the most basic and most used form of light switch used to.
