A two way switch has 3 terminals. Never work on an electrical circuit while it is hot. Connecting electrical devices and appliances like fan, outlet, light bulbs etc in parallel is a prefer way instead of series wiring. Straight forward and easy to understanding! The schematic shows that the circuit is complete and the bulb is on. But in some case, we need to wire and connect electrical appliances in series as well. The 14/3 cable connects the 2 switches. the, Any number of lighting points or load can be added (according to the circuit or sub-circuit load calculation) in this kind of circuit by simply extending the, another major defect of series lighting circuit is that as all lamps or bulbs are connected between Line. When wiring a 2-way switch circuit, all you're really doing is controlling the power flow (Switching off/on) to the load (a light, lamp, outlet, ceiling fan etc..) Now a typical circuit will contain a 3-wire cable known as romex. Below is a given schematic wiring diagram (fig 2) that shows how to wire a 2-way switch and control a light bulb from two different places. Two-wire cable runs from the combo to the light fixture and the switch output is connected to the black wire running to the fixture hot terminal. The lifespan of battery in series circuit is more as compared to parallel. Disconnect the power source before servicing, repairing or installing electrical equipments. Connect one wire to the first switch in the box and the second wire to the other switch, and connect the black wire from each of the lights to the other terminal on its respective switch. Read all instruction and cautions and follow them strictly. It is a little more involved than simply wiring a switch at the end or in the middle of a circuit, mainly because there are more wires and connections involved. A common(C), L1 and L2. EE-Tools, Instruments, Devices, Components & Measurements. When wiring a 2-way switch circuit, all your really doing is controlling the power flow (Switching off/on) to the load (a light, lamp, outlet, ceiling fan etc..). If we add more loads in series circuit, the over voltage drop is increases which is not a good sign for electrical appliances protection. One is an older method, which is not often used now-a-day… Here, you can see there is a cut in the line wire connected to lamp 3, so the bulb is switch OFF and the rest circuit is working properly i.e. The first two way switch is quite easy to wire up. If more lamps are added in series lighting circuit, they will all be reduced in brightness. The white, or neutral, wires bypass the switch, so the one coming from the power source and the one from the light get spliced and capped in the box. The Two way switch costs more and the material and components and wiring required is more than one way switch. You're going to need to … Multiple lights between 2 3-way switches, with additional lights beyond the second switch. This type of switch lets you turn the light off or on from more than one place in the room. Each lamp is connected to the next one i.e. At the beginning of the circuit the hot source is connected to the common terminal on SW1. Strip 1/2 inch of insulation from the leads on both ends of the electrical wire with your wire cutters. The red wire connects the switches normally open terminals, and the black wire connects the normally closed terminals. The second option allows you to easily disconnect fixtures you no longer want to use, but it becomes cumbersome when more than two fixtures are involved.
