A single-pole switch has two brass terminal screws on the side that connect to the electrical circuit’s black (“hot”) wires. One black wire comes from the power source (theelectrical panel) and the other goes to one or more light fixtures. When the switch is on, electricity flows thr...
Electricians use a continuity test to determine if there's a break in the circuit, so the fixture must be isolated from power to get a reading. If you have a plug-in lamp, you can just unplug it, but if you're testing a wall or ceiling fixture, you need to disconnect it from the...
Shut off the circuit that sends power to the dryer (or the appliance that hooks into the 220-volt outlet) at the circuit breaker box. Then, take off the outlet cover and remove the outlet from the box. This will require loosening the screws holding the wires inside the outlet. Step 2 ...
A switch is like a drawbridge in an electric circuit. When the switch is closed, the "bridge" is down and electric current can flow around the circuit; when the switch opens, the "bridge" is up and no current flows. So the purpose of a switch is to activate or deactivate a circuit ...

Now that we know that your coil is good, we’ll want to test the switch pins. These pins are a Normally Open (NO) circuit, meaning that they are open by default and have no continuity. There should be no load traveling through it until the circuit is closed by energizing the relay....
