In an electrical context, the term "switched" refers to a circuit that can be opened or closed to control the flow of electricity. This means that by actuating a switch, the user can either allow electricity to pass through the circuit and power devices or disconnect the circuit to stop the flow of electricity. This on/off control is fundamental in electrical systems, enabling the operation of various devices as needed while providing safety precautions by allowing circuits to be deactivated.

The other options represent different concepts within electrical systems. For instance, voltage regulation pertains to devices designed to maintain voltage levels at a stable point but does not involve the direct on/off manipulation of circuit flow as a switch does. Similarly, a wire alternating between circuits addresses circuit selection and routing but does not inherently define the control aspect of electrical flow associated with switches. A circuit with multiple power sources describes specific configurations related to energy supply but again doesn't encapsulate the essence of being switched, which is fundamentally about controlling connectivity in the circuit.
