WebMar 19, 2024 · A 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. http://cdn.crouzet-switches.com/assets/library/Sidebar/microswitches_basic_technical_concepts_EN.pdf
