Difference Between Single And Double Pole Light Switch

It has four terminals.

Difference between single and double pole light switch. Two for incoming hots and two for outgoing hots. A double pole switch is what you need to control a 240 volt device because 240 volt circuits have two hot wires. A four way has four. Electrical wiring difference between single pole double pole switches pole explained.

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. 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.

The main difference is that a double pole switch has four hot brass terminals instead of two plus a ground terminal.

The most common household switch a single pole has two terminals and simply turns power on or off.

This allows the user to connect it to two pairs of hot wires from a 240 volt circuit. A three way switch has three terminals. Because a single pole switch controls a single fixture it has two fixed positions. Well single pole breakers and double pole breakers differ in the voltage and amperage they provide as well as how they are wired.
