What is a double pole switch used for?

A double pole switch is a type of electrical switch that is used to control the flow of electricity to two separate circuits simultaneously. It has two separate sets of contacts that open and close together when the switch is turned on or off. This means that it can control the power supply to two different appliances or circuits at the same time.

Double pole switches are often used in applications where two separate circuits need to be operated independently. For example, they are commonly used in homes to control lighting fixtures in different areas of a room or to control the power supply to two different appliances.

They are also commonly used in industrial settings where multiple circuits need to be controlled simultaneously, such as in machinery and equipment that require multiple power sources.

Double pole switches are typically more expensive than single pole switches because they have more complex internal mechanisms. However, they offer greater flexibility and control over electrical circuits, making them a popular choice for a variety of applications.
