What is the purpose of a general-use switch in electrical installations?

The purpose of a general-use switch in electrical installations is primarily to isolate an electric circuit from the source of power. This means that when the switch is in the 'off' position, it disconnects the electrical circuit, ensuring that no electrical current flows to the connected devices. This function is crucial for safety, maintenance, and repair of electrical devices, as it allows individuals to work on a circuit without the risk of electric shock.

General-use switches are designed to control the flow of electricity manually, making it easy for users to turn on or off devices as needed. This is particularly important in residential and commercial settings for light fixtures, outlets, and appliances. The ability to isolate a circuit holds significant importance when it comes to ensuring safe handling and operation of electrical systems.

Regulating voltage fluctuations, connecting multiple circuits simultaneously, or switching power on and off automatically are functions that pertain to other types of devices or equipment but do not represent the primary purpose of a general-use switch.
