AnswerAccording to my husband, all sockets are double pole, single and double pole refer to switches. Hope that helps. Double pole isolates both neutral and live, single pole only isolates live, double is better, but single is cheaper. DP-switched sockets have only become commonplace in relatively recent times anyway, marketed on yet another "increased safety" angle when there was never any safety problem with SP to begin with.
When switches or any circuit opening devices are in series with each other, they all have to be in the closed position to energize the load.When switches or any circuit opening devices are in parallel with each other, any one of the switches or circuit opening devices in the closed position will energize the load.
All of these types of devices have different applications and usually are of different physical sizes. If you are talking about poles and confusing it with gangs then; A 2 pole is a double pole single throw switch. A 3 pole switch is usually used as a manual transfer switch for three phase applications. A 4 pole, never heard of one. A 1 way or single pole switch is the same type of switch used in home circuits to turn the lights on and off. The term gang in the electrical trade refers to electrical junction boxes (usually for switches) that are joined together to make an installation compact by keeping all of the switches in a common place. A single "hot" circuit is brought in from the distribution panel and pigtailed to each individual switch. The bottom of the switch then connects to the individual lighting loads.
To fix a tripped breaker, locate the tripped switch in the breaker box and flip it all the way to the "off" position and then back to the "on" position. If it trips again immediately, there may be an underlying issue causing the problem, and you should consult a licensed electrician for further assistance.
A single pole two-way switch, also known as a SPDT switch, is a type of electrical switch that can control one circuit from two different locations. It has three terminals: common, and two travelers. It is commonly used for controlling a light fixture from two different locations, such as at the top and bottom of a staircase.
A single-pole two-position switch -- also called a single-pole double-through (SPDT) switch -- is a manually-operated device that can be pushed to one of two states: the common terminal makes contact with the L1 terminal, and is isolated from the L2 terminal; or the common terminal makes contact with the L2 terminal, and is isolated from the L1 terminal. Other two-position switches have more than one pole, acting like several SPDT switches that are electrically isolated but mechanically connected so they all move from one state to the other together. When more than one light switch controls a light bulb -- "three way" and "four way" light switches -- each switch is a two position switch.
A double pole switch can be used in either a 240V application where you'll need to disconnect 2 "hot" lines, or it is useful when switching a light from 3 different switches. Disadvantage? I suppose it could be a little confusing to face all those contacts on a double pole switch.
Three way switches do not have a up-on down-off position. With the lights off, reposition the switches so that the handles are all down. This is the start position and depending on how you enter the room and turn on the lights certain switches will be left up when you leave the room. That is just the design of the switches and for the asthetics of the look, all handles down the lights will be out.
A switch is inserted in series with a single wire. When the switch is on, it is as if the wire had not been opened to insert the switch. When the switch is off the wire is open and no current can flow. All a double pole switch does is allows you to switch two separate wires at the same time with the same switch action. A single pole switch just switches one wire.
You seem to be referring about a 3 way lighting circuit. If the cross over switch is replaced with a double pole switch, depending on how the switch was wired into the circuit, the load lamp would either stay on or not light at all. A circuit in a three way configuration has two traveler legs between the two switches The intermediate switch in the circuit just switches the two traveler legs from open to close depending on the position of the other two switched. Google, three way switching, they have many diagrams to work from.

The world record of pole position was 71,460 by Hiro japasxan from Horisananai, Mongolia and the American record of pole position was 71,040 by Skaroley cavernly from Scotsdale, Arizona. This all happend at the 2006 video racing championship of pole position and neither of them won that championship. The winner was Kalvin jaspeck from Price edward island in Canada and his best was 66,820 of his pole position career.
The two outside switches go halfway down, and the middle one all the way down.

In order for the load to be energized in a circuit with multiple switches in series, all the switches must be closed or in the "on" position. This is because switches in series function like an "AND" gate in digital logic, requiring all inputs to be true for the output to be true. If any one of the switches is open or in the "off" position, the circuit will be open and the load will not receive power. Therefore, all switches must be closed to complete the circuit and energize the load.
