Question

Quizplus · Accepted Answer

A relay can be used to switch high currents without the need for heavy wiring to be routed to the switch location. The relay can be located closer to the load, with smaller wiring used to connect to the load, while the control circuit can be located further away where it is practical to route control wiring. Electromagnets and solenoids are not ideal for switching applications as they are typically used for linear motion and not for switch control. Generators generate electricity and are not suitable for switching applications.
