A single pole switch controls one circuit, while a double pole switch controls two separate circuits.
Answer for USA, Canada and countries running a 60 Hz supply service.The difference between a double pole switch and a single pole switch is the use of the switch in the installation or equipment. A double pole switch is used when the voltage from two circuits has to be broken. An example of this is a 240 volt supply. A single pole switch is used where there is only a single supply voltage that has to be broken.
A single pole light switch controls one circuit and has one switch, while a double pole light switch controls two circuits and has two switches.
A single pole switch controls a light or outlet at one location. A 3 way switch controls a light or outlet from 2 locations.
A single pole light switch controls one light fixture from one location, while a double pole light switch controls one light fixture from two locations.
In single replacement reactions, one element replaces another element in a compound to form a new compound and element. In double replacement reactions, the positive and negative ions in two compounds switch places to form two new compounds.
A single pole switch interrupts only one wire, which must be the live wire. A double pole switch interrupts both the live and the neutral, so it contains two separate switches operated by the same lever. Current practice is to use single-pole switches, to avoid a fault condition which could leave equipment live while switched off.
no difference whatsoever
Single-pole, double-throw. The switch directs a single input to two possible outputs.
No it is not hard to tell them apart. A Single Pole Single Throw switch will go directly from the on position to the off position breaking the circuit. This is the type of switch that is used in homes for lighting control. A Single Pole Double Throw switch will usually have a stop indent which is the off position mid way through the throw. This is the switch that is used for a transfer switch when using a stand by generator in the system. The full up (on) position is usually connected to utility power. The full down (on) position is usually connected to the stand by generator.
A double pole switch is used to control two separate circuits simultaneously, while a single pole switch only controls one circuit. This means that a double pole switch can completely disconnect both the hot and neutral wires, providing a higher level of safety and control compared to a single pole switch.
A double pole light switch controls two separate circuits, while a single pole light switch controls only one. Double pole switches have four terminals for wiring, while single pole switches have two.
A double pole single throw switch. used to switch two lines at the same time.
