Most standard 120 volt household circuits in your home are or should be parallel circuits. For example two circuits that each use a pair of spst switches to turn a lamp on or off.
3 Way Switch Variations
Wiring switches in parallel. The common household circuits used in electrical wiring installation are and should be in parallel. More wires and cables are required in parallel wiring connection. To wire in the parallel master switch you are going to connect the mastercell inputs for the drivers and passengers switch together and bring them to the parallel switch. Just as lamps can be connected in series or parallel in an electronic circuit switches can also be connected in series or parallel. Switches connection in parallel is a prefer way to wire home appliances. It is a reliable and comfortable.
Wiring a 3 way light switch. Switches and fuses must be connected through line live wire. Parallel or series parallel wiring method is. These diodes are electrical check valves. Outlets switches and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit. Mostly switches outlet receptacles and light points etc are connected in parallel to maintain the power supply to other electrical devices and appliances through hot and neutral wire in case if one of them gets fail.
With a pair of 3 way switches either can make or break the connection that completes the circuit to the light. In the first circuit the switches are wired in series. The important thing here is that you need to put a diode on each of the wires from the drivers and passengers switch. Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram. In the second the switches are wired in parallel.
