Is simple terms, yes. Power to switch, when switch is turned on it will send power to pin 86. Pin 86 and 85 are each side of a magnetic coil. When the coil is energized it pulls down a bar that makes contact between pin 30 and pin 87 which passes power to compressor. So yes there are 2 separate electrical circuits in the relay.
NOTE: Any incorrect spelling is intentional to prevent those annoying popups.

Big minds talk about ideas..small minds talk about people.
