How do you run two lights from one switch?

How do you run two lights from one switch?

Green to ground, the timer's white wire to the neutral (white wires) splice in the box, the timer's black wire to the hot conductor (one of the two on the existing switch), and the timer's red wire to the black wire on the existing switch that is connected to the lights. The new switch should have three terminals: black, red, and ground.

Now when you turn off the main switch, the timer will keep the lights on for an hour after they've gone out. When the timer expires, the red wire will connect both lamps to the opposite pole of the battery, thereby turning them off.

This arrangement saves energy by not having both lights come on when the main switch is turned on. It also keeps traffic signs readable at night, since other people can still see them even if their own lights are off.

Two light circuits are always assumed to be independent, so they can't share a common switch or power source. But this is often the case with exterior lights. If your lights are wired in a parallel circuit, then either all of them will work whenever the main switch is turned on, or none of them will work at all.

Exterior lights must be kept in good working order. Have any bulbs burned out? Replace them immediately before an accident can cause more damage. And don't forget about headlight polarity!

How do you hook up a light switch?

Connecting a switch is the epitome of simplicity. The black wires in the electrical box are connected to the switch terminals, while the white wires are connected to each other. In addition, the switch contains a green terminal for the ground wires, which are generally bare. All you need to do is connect them together as shown below.

There are several different types of switches, but they can be divided into two main categories: toggle and rocker. A toggle switch allows you to choose from two states: on or off. It does not stay in any one state; instead, it goes back and forth between the two positions. A rocker switch has three or four positions: off to the left, off to the right, on top, or on bottom. It stays in one position until you move it to another position.

Both toggle and rocker switches are easy to connect. First, determine which side of the switch controls which part of the system by reading the instructions that come with the switch. Then match up the black wires at both ends of the wire connector. If the black wires are the same length, then they belong to the same circuit. If they are not the same length, then they don't go to the same place and you will have to replace the entire switch assembly with one that has equally long black wires.

Switches are available in many different styles.

How do you install an electric light switch?

Replace the light switch. Holding their stripped ends side by side, screw on a wire nut to connect the two white wires. Connect the bare ground wires in the same way. Insert the wires inside the box. Make loops using the two black wires. Connect them to the switch's two terminals, and...

Where should the hot wire go on a light switch?

The black (hot) wire is connected to the brass screw or a hole on the rear of the device on the same side as the brass screw. This wire is occasionally red. If the device has one, the green or bare copper (ground) wire connects to the green screw terminal on the switch or to the electrical box. Otherwise, connect the ground wire to the metal chassis of the device.

The white (neutral) wire is attached to the silver screw or a hole on the back of the device on the opposite side as the brass screw. This wire is always live and cannot be used as a conductive path on the switchboard. However, it can be used to feed additional devices if necessary. White wires are not colored inside walls and boxes; therefore, they must be identified with tape or some other method before they are routed to equipment that may cause injury if contacted.

The term "switch" as used in this book refers to a mechanical device that opens and closes an electric circuit. A switch controls power to a load by connecting it to either a +120-volt AC line source or no source at all. The load will receive power only when the switch is in its ON position. When the switch is in its OFF position, no power flows into the load.

Switches come in two varieties: toggle and rocker. A toggle switch has three terminals: two fixed contacts and a middle contact that moves back and forth between them.
