What is a single pole switch used for?

A single pole switch is specifically designed to control a single lighting circuit from one location, making it straightforward and efficient for managing lights. When the switch is in the “on” position, it completes the circuit, allowing electricity to flow and the light to illuminate. Conversely, when it is turned “off”, it breaks the circuit, causing the light to turn off.

The primary purpose of a single pole switch is to operate one device, such as a light fixture, and to do so from one location. This functionality enhances usability and simplifies wiring in residential and commercial electrical systems. In contrast, options that involve controlling multiple devices at once or remotely pertain to different types of switches, such as 3-way switches or smart switches, which have additional characteristics and functionalities beyond the basic single pole design. Additionally, increasing voltage in a circuit relates to transformers or power supplies, which is unrelated to what a single pole switch does.
