Control Relays (Full lecture)

In this lesson we'll introduce the control relay, an electromechanical device that forms the principal logical element of an electrically controlled system. Relays can perform numerous functions by selectively energizing or deenergizing other elements within the system or between two separate systems at the appropriate moments to coordinate and sequence activity.
