| My take is that + and - are battery. Common is the line to the load you want switched. At rest the contact between n/o is open, but the other, n/c is closed. When triggered, it is the opposite. A wag is the coiled wire is the trigger?
Usually an a 5 wire solid state relay, the coil gets energized when it receives power and that flips the internal switch.
The terms n/o and n/c are definitions when the switch or relay is at rest with no input or power. | |

Simple remote relay hookup, but I want to make sure
