Question

Quizplus · Accepted Answer

A timer is specifically designed to control the flow of electricity for a certain amount of time. A four-way switch and single-pole switch are devices used to control the flow of electricity on a circuit, but they do not have a time control function. A motion sensor is used to detect motion and trigger a response, but it does not necessarily control the flow of electricity on a circuit for a set amount of time.
