Best Answer

There are three types of relay. Normally open relays mean the electric current can't pass until something causes the relay to close and complete the circuit. Example: when you start your car you are closinga relay when you turn the key and the circuit to the starter is allowing electricity to the starter. Normally close relays mean the circuit always has electricity unless you do something to stop it. Last but not least is a switching relay where the power is switched from one circuit to the next. Example: headlights bright to dim also dims or brightens the dash lights.
