Question

Quizplus · Accepted Answer

Technician A is correct because a switch is indeed considered a circuit control device, as it can open or close a circuit, thereby controlling the flow of electricity. Technician B is incorrect because a relay's primary function is not to reduce voltage but to allow a low-power circuit to control one or more higher power circuits.
