Hooking up two light switches

How to separate two lights on one switch

The Green screw on the 2-way switch is for the ground so all ground wires should be connected as seen below. The receptacle is split by breaking the connecting tab between the two, brass colored terminals. For each fixture and switch you have the choice of nailing a rough-in box to a stud or rafter or mounting a remodeling box on the drywall. Multiple Light Wiring Diagram This diagram illustrates wiring for one switch to control 2 or more lights. The black cable wire runs to the SW1 connecting it to the hot on the top half of the split outlet. If you are running a new circuit, check the electrical code to understand this and any other updates to the required procedure. This is another option for wiring a combo device where two electrical sources are used. Let's assume the load you are controlling is a light. Because the electrical code as of the NEC update requires a neutral wire in most new switch boxes, a 3-wire cable runs between the light and switch. Install appropriate electrical boxes for the lights and switches. Now in the diagram above, The power source is coming in from the left. The source is at the switch box and a 2-wire cable is run to each light. The dimmer switch will have stranded wires that must be sliced to the solid cable wiring in a pigtail fashion. You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2-way switch and a black wire from the other screw on the 2-way switch going to the load light, ceiling fan etc.. One source is spliced to each switch with a pigtail to power the two lights.

The tab between the neutral, silver terminals should remain intact. Twist all the white wires in each electrical box together and cap them.

Form a similar pigtail with the ground wires. You maintain the continuity of the hot wire in the circuit cable by forming pigtails at the points where it connects to the switches. Check local regulations for restrictions and permit requirements before beginning electrical work. In this case, there will be three black wires forming the pigtail: two 6-inch wires coming from the switches and one circuit wire. Pull one end of each cable through the back of one of the light fixture electrical boxes. In this updated diagram, 3-wire cable runs between the receptacle and SW2 to allow for splicing the neutral source through to the second switch box. The source hot wire is connected to a switch terminal and the other terminal is connected to the black cable wire. Dimmer Switch Wiring Diagram A rheostat, or dimmer, makes it possible to vary the current flowing to a light fixture thereby varying the intensity of the light. The neutral from the source is connected directly to the neutral terminal on the light and the source hot is spliced with the white loop wire. Twist the other end together with the black wire from the incoming circuit cable and the black wire from the cable going to the second switch to form a pigtail. Twist a wire cap onto the end of the pigtail. Let's assume the load you are controlling is a light. The black wire to SW2 is connected to the hot on the receptacle and to the common on SW2 at the other end. Like the split receptacles previously mentioned, these devices make use of a removable connector between the two hot terminals to divide it when needed. Wiring a Switch Loop When the electrical source originates at a light fixture and is controlled from a remote location, a switch loop is used.

Here again, the connecting tab between the receptacle terminals is broken off and the neutral tab remains intact. At SW1 it is connected to one of the terminals.

Wiring a two way light switch with double switch

The white wire is marked black on both ends to identify it as hot. The switch output is sent to the hot side of the receptacle using a short jumper wire of the same gauge. With this arrangement, two lamps can be plugged into the same outlet and each can be controlled separately from two different locations. Typically, the source is a circuit breaker in the main electrical panel that has a rating large enough to handle the lights. The source is at SW1 and 3-wire cable runs from there to the outlet, 2-wire cable runs from there to SW2. This simple diagram below will give you a better understanding of what this circuit is accomplishing. After you have pulled your switch out from the wall, the wires in the box and connecting to the switch should look like one of the following. Connect one end of the 6-inch wire to the top terminal of the first switch. Pull a gauge cable from the power source, making sure that the power is off and the cable is dead. Now by understanding the diagram above, go up to the top diagram and by using the concept shown here, just use your mouse pointer on that diagram and follow the flow from black wire hot wire to the load and return through the white wire neutral. Wiring a 2-Way Switch How to wire a 2 way switch. This is an updated version of the first arrangement.

At the outlet, the travelers are spliced to run to SW2 using the red and white wires in that cable. Twist the other end together with the ends of the three bare wires in the box. Use the other 6-inch wire to connect to the top terminal of the second switch if it is mounted in the same electrical box.

We use a receptacle here but any device such as a switch, timer, etc.
