How to change a fuse in a wall switch
Have you ever tried to turn on a light switch, only to find that the lights won’t come on? This could be due to a blown fuse in the wall switch. Don’t worry, changing a fuse in a wall switch is a simple task that you can do yourself without the need for an electrician.
Wall switches have fuses installed to protect the circuit from unexpected power surges. When a power surge occurs, the fuse is designed to blow, breaking the electrical circuit and preventing potential damage. Fortunately, replacing a blown fuse is relatively easy and can be done in just a few simple steps.
Before you begin, it’s important to remember that safety should always be your top priority when working with electricity. Make sure to switch off the power at the circuit breaker before attempting to change the fuse in a wall switch. This will prevent any potential electric shock.
To change the fuse, begin by removing the cover plate of the wall switch using a screwdriver. Once the cover plate is removed, you will find the fuse holder behind it. In most cases, the fuse holder will have a small tab or handle that you can use to pull it out.
With the fuse holder in hand, inspect the fuse closely to determine if it is blown. A blown fuse will have a broken metal strip and will appear darker in color compared to a functioning fuse. If the fuse is blown, remove it from the fuse holder and replace it with a new fuse of the same rating.
It’s important to note that fuses come in different ratings, so be sure to choose a replacement fuse with the correct amperage. Insert the new fuse into the fuse holder and push it in firmly until it is securely in place. Once the new fuse is installed, reattach the fuse holder and cover plate, and restore power at the circuit breaker.
In conclusion, changing a fuse in a wall switch is a simple task that can be done by anyone, as long as the necessary safety precautions are taken. By following these easy steps, you can ensure that your lights will turn on again with just a simple flick of a switch.

Turn off the electrical supply
Before attempting to change a fuse in a wall switch, it is crucial to ensure the electrical supply to the switch is turned off. This will help prevent any accidents or electric shocks while working with the switch.
To turn off the electrical supply, follow these steps:
- Locate the circuit breaker panel or fuse box in your home.
- Open the panel or box cover.
- Identify the circuit or fuse that provides power to the specific room or area where the wall switch is located.
- If you have a circuit breaker panel, find the corresponding switch or lever for that circuit and move it to the “off” position. If you have a fuse box, carefully remove the fuse for that circuit and safely store it to the side.
- Once the circuit or fuse is turned off, test the wall switch by toggling it on and off to ensure there is no power flowing to it.
Remember to use caution when handling electrical components and to never touch exposed wires. If you are unsure about any aspect of the process or do not feel confident performing these steps, it is recommended to seek the assistance of a qualified electrician.
Remove the wall switch cover
To change a fuse in a wall switch, the first step is to remove the switch cover. Make sure the power to the switch is turned off at the circuit breaker before you begin. This will help prevent any potential accidents or injuries.
Start by using a screwdriver to remove the screws holding the switch cover in place. Depending on the type of switch cover you have, there may be one or two screws.
Once the screws are removed, gently pull the switch cover away from the wall. Be careful not to apply too much force, as this can damage the switches or the surrounding wall. In some cases, the switch cover may be secured with plastic tabs that can be pressed inward to release the cover.
With the switch cover removed, you will be able to access the fuse inside the wall switch. Take a moment to inspect the switch and the surrounding area for any visible signs of damage or wear.
It is important to note that if you are uncertain about any part of the process or if you are not comfortable working with electricity, it is best to call a professional electrician to perform the fuse replacement.
