Final answer:
A general-use switch that can be installed in device boxes or used with recognized wiring systems is known as a wall switch, which is a component of electrical safety systems. Electrical safety is further ensured by devices like circuit breakers and three-wire systems that protect against both thermal and shock hazards.
Step-by-step explanation:
A form of general-use switch that can be installed in device boxes or on box covers, or used in conjunction with wiring systems recognized by the code, is commonly referred to as a wall switch or toggle switch. These switches are part of electrical safety systems designed to control the flow of electricity and prevent hazards such as electrical shocks or fires.
Electrical Safety: Systems and Devices address the variety of devices used to ensure safety in electrical systems. For example, circuit breakers and fuses are used to interrupt excessive currents, while the three-wire system—which includes live/hot, neutral, and earth/ground wires—provides protection against both thermal and shock hazards by grounding the neutral wire and the case of the appliance.
