When voltage is applied to the input terminal, current flows through the coil and creates a magnetic field. This, in turn, closes the switch, which then energizes the load. The time delay starts when the coil is energized. When the preset time has elapsed, the switch opens, de ... WebA relay is a solenoid set up to actuate switch contacts when its coil is energized. Pull-in current is the minimum amount of coil current needed to actuate a solenoid or relay from its “normal” (de-energized) position. Drop-out current is the maximum coil current below which an energized relay will return to its “normal” state. feribot lefkada kefalonia
