How to Wire a Doorbell from a Light Switch

Doorbells are usually powered through a doorbell transformer, which has to be professionally mounted so that it can carefully extract power from your electrical system.

But you can connect your doorbell to a light switch. It will not only provide enough electricity to function but also an additional source to turn the doorbell on or off just by using a light switch.

If you already have working doorbell chimes and transformers wiring process becomes simple and convenient.

Adding an outlet from a light switch is straightforward, and it takes just a few dollars and a little time to do.

But it is important to know the proper method to perform a wiring process for connecting a new or existing doorbell from a light switch.

How to Wire a Doorbell from a Light Switch

If your home electrical system for a doorbell isn’t prepared and set yet, it is practical enough to consult an electrician.

Before wiring the doorbell switch with light and working with electrical wires, you must ensure your safety, use a voltage sensor to make sure that the power is off.

Follow these steps carefully to complete the wiring process conveniently.

Step 1: Unscrew Existing Doorbell

While wiring an existing doorbell to a light switch you can start by unscrewing the doorbell. Locate the screws used to mount the doorbell to your outer wall or door casting. Unscrew them using a screwdriver or a power drill.

It will expose the internal wiring of your doorbell allowing you access to modify the system and link it to the light switch.

You can easily work with the wiring inside by testing and locating the feasible one for attachment.

Step 2: Find the Doorbell’s Hot Wire

You have to find the hot wire i.e. the one with enough electric current supply. The wire is easy to locate, mostly in black and wider than other wires. But the specifications may differ based on the brand of doorbell you use.

There is another way of distinguishing the hot wire from the live current. You can use a voltage tester to test each of the wires separately.

The best way to do so is to turn the switch off and test all of the black wires by placing one of the leads of a voltage tester on the wire and the other one on the ground screw.

Carefully observe, the tester will light up when you attach it to a live wire. You also have to identify a neutral wire from the light switch as well to create a link.

Once you have identified the wire, turn the circuit breaker off before starting the wiring procedure for absolute safety.

Step 3: Find the Neutral Wire for Light Switch

The next step is to identify a neutral wire from the light switch for making a secure connection. If the doorbell doesn’t have a built-in light, you can easily link it to any natural wire from a light switch.

A doorbell switch with a light built-in is comparably easily connected.

Go to the switch box of your house and follow the hot wires to the switch that has full control over the circuit powering the doorbell.

This wire is also can be readily located. It is usually white and is thinner as compared to other surrounding neutral wires in the switch box.

Now you have to link both of the wires together to secure a connection for wiring a doorbell from a light switch.

Step 4: Wire the Doorbell to the Light Switch

Take the black wire from the doorbell and connect it to one of the neutral hot wires from the switch box. You can start by disconnecting the black wire from the doorbell and splicing it together with the wire going to your outlet.

You will also require a certain length of exposed copper wire. Make sure the wire is approximately an inch longer than the needed length.

Connect one side of the exposed copper wire to the splices doorbell cable.

Then, connect the other end of the copper wire to any of the hot wires from the switch box to make a connection in between. You also have to connect the white neutral wire from the switch box as well.

Step 5: Wire the Neutral Wire

Attach the white neutral wire from the switch box to the neutral copper wire coming from the outside. By this method, you can connect the doorbell to the light switch in no time.

The doorbell wired to the light switch will ring whenever you flip on the light switch.

If the bell doesn’t ring you have to try rewiring everything once again. It is vital to ensure the copper wire is completely covered and concealed. It shouldn’t be touching any wires or other metal parts.

Step 6: Hide Your Wires

You have to conceal the wires after the wiring process to ensure the durability of your wiring system.

You can arrange the wires and hide them behind your furniture so that they are not seen by anyone. Concealing the wires also saves them from any damage.

Make sure that any exposed copper is capped off with electrical tape or wire nuts to save it from wire cutting or chipping so that the system can last longer.

You can use the same method for wiring a ring doorbell to a light switch.
