It is that sinking feeling when you flip the light switch on or running the garbage disposal in the kitchen sink and nothing happens that is when it is handy to know that a typical light switch is a single pole single throw switch and, chances are, the operation of a garbage disposal relies on a double pole single throw switch. Light switch double pole. A switch is a device that is used to control current flow in an electrical circuit a simple switch provides electrical connection between two terminals when a conductor connected to one terminal is brought into contact with another terminal there are two types of pole switches, namely: the single pole and the double pole switch.
light switch double pole
A double-switch allows you to operate two lights or appliances from the same location double switches, sometimes called "double pole," allow you to separately control the power being sent to multiple places from the same switch for example, you might want to turn on a bathroom light separately from the ceiling fan to wire a double switch. A double pole single throw (dpst) switch controls the connections to two wires at once, where each wire only has one possible connection. in other words, it's like two simple switches controlled by a single actuator. the dpst switch often appears in circuit breakers, where it is used for 240-volt circuits, with each pole carrying 120 volts.
