single-pole
A "single-pole" refers to a type of electrical switch or circuit that controls a single circuit or device. It typically has two positions: on and off. When the switch is in the "on" position, it allows electricity to flow, powering the connected device, such as a light bulb or fan.
In the context of electrical systems, a single-pole switch is commonly used in residential settings for simple lighting controls. It is straightforward to install and operate, making it a popular choice for homeowners. This type of switch is often found in conjunction with wiring and circuit breakers in electrical panels.
