A Double Pole Switch is an electrical switch that controls two separate circuits simultaneously. It has two sets of contacts, allowing it to interrupt both the live and neutral wires in a circuit. This feature enhances safety by ensuring that the entire circuit is disconnected when the switch is turned off. These switches are commonly used in high-power applications, such as in home appliances or industrial equipment, where it is essential to cut off both the live and neutral connections. By doing so, they help prevent electrical shocks and ensure proper operation of devices that require a higher voltage.
