Removing a round electrical switch plate can be a simple task, but it's important to exercise caution when dealing with electrical fixtures. Before attempting to remove the switch plate, ensure that the circuit breaker connected to the switch is turned off. This is a crucial safety precaution to avoid the risk of electrical shock. Once the power is cut, use a screwdriver to gently prise the switch plate off the wall. If there are visible screws, remove them first. If the switch plate has no screws, look for a slot to pry or use a flat-head screwdriver to gently push it off. Be careful not to apply too much force, as this could damage the wall or the switch plate. If the switch plate is glued to the wall with paint or wallpaper, carefully peel it off to avoid damaging the surrounding area.
Characteristics and Values Table for Removing a Round Switch Electrical Plate
| Characteristics | Values |
|---|---|

What You'll Learn
Before starting, cut the power to the circuit
Before starting any work on your electrical switch plate, it is imperative to cut the power to the circuit for your safety. Working on a live circuit can be extremely dangerous and should be avoided at all costs.
To begin, locate your home's electrical service panel, which is typically a large grey metal box attached to a wall somewhere in or around your home. This box contains the circuit breakers that control the flow of electricity to various parts of your house. Once you have located the panel, open it up and look for the breaker responsible for the circuit you are working on. It is a good idea to turn off the main breaker as well, just to be safe.
After turning off the breakers, verify that the power has indeed been cut. You can do this by testing several outlets with a non-contact electrical tester or by flipping the switch a few times to ensure none of the lights are receiving power. Only when you are absolutely certain that the power is off should you proceed with removing the electrical plate.
It is worth noting that in many places, you may be required to be a licensed electrician to work on wiring. So, if you are not confident in your abilities or are unfamiliar with electrical work, it may be best to consult a professional.
Additionally, older homes built before 1965 may have fuses instead of breakers. In this case, you would need to remove and replace the fuses in the fuse box to turn the power off and on. These fuse boxes are usually smaller white boxes located on an exterior wall of the home.

Use a flat-head screwdriver to gently prise off the plate
Before you begin, ensure that you have cut off the power supply to the electrical plate by switching off the circuit breakers. This is important for your safety.
Now, to remove the electrical plate, you will need a flat-head screwdriver. Insert the flat-head screwdriver into one of the small slots or notches on the plate. You may need to gently poke around the edge of the plate to find a good place to insert the screwdriver. Once you have inserted the screwdriver, gently prise the plate off the wall by applying a gentle helping push or a little force. Be careful not to apply too much angular pressure, as this could cause the plate to crack and damage the wall.
If the plate does not come off easily, you may need to gently pry on two sides of it simultaneously to see if it will slide off. Alternatively, you can try using a small pair of bent-nose pliers to remove the plate, especially if there are spanner nuts holding the switches in place.
Once the plate is removed, you may need to disassemble any screws holding the internal section in place. Be cautious when removing old plates that have been glued to the wall with paint or wallpaper, as this can damage the surrounding area.

If glued, carefully peel the plate away from the wall
If the electrical plate is glued to the wall, you will need to carefully peel it away. Before you begin, ensure that you have cut the power to the socket and switched off the electricity to the circuit breakers connected to the switch.
The plate may be glued to the wall with paint or wallpaper. You can use a razor blade or utility knife to cut the paint around the edge of the plate to help free it. Be cautious when doing this so as not to damage the wall or the rest of the surrounding area.
If the plate is glued with wallpaper, you may need to gently pry the plate away from the wall. You can use a flat-head screwdriver or another flat instrument to do this. Gently push the screwdriver between the plate and the wall, and slowly work your way around the edge of the plate.
In some cases, the plate may have been on the wall for so long that it is difficult to remove, even if it is not glued. In this case, you can use a thin, flat blade screwdriver or a razor blade to carefully pry the plate away from the wall. Start from the underside, and if you mark the surface, it won't be visible.
If the plate is glued with a strong adhesive, you may need to use a stronger tool such as a pin spanner wrench or needle-nose pliers to remove it. You can also use a pair of pliers to grasp the round nut and turn it counter-clockwise.

Identify the bad switch and remove it from the plate
If you notice any of the following issues, your light switch may be faulty:
- Flickering lights
- Sparks, especially if they are large or have gotten bigger
- Unusual noises, crackling, or buzzing
- The switch is warm to the touch, unless it is a dimmer switch
- Physical damage, such as cracks, breaks, or discolouration on the switch cover plate or switch plate
- Experiencing an electric shock when touching the switch
If you suspect that your light switch is faulty, follow these steps to identify the bad switch and remove it from the plate:
- Disconnect the power to the switch at the circuit breaker.
- Remove the switch cover plate. Depending on the type of plate, you may need to use a Stanley knife or a small screwdriver to prise it off. If the plate is stuck due to paint, use a razor blade or a thin, flat blade screwdriver to cut through the paint.
- With the cover plate removed, you will be able to see the switch and its wiring. Unscrew the mounting screws holding the switch in place.
- Gently pull the switch out from the electrical box to fully access the wiring.
- Inspect the switch for any signs of damage, such as damaged wiring, loose wires, or burnt terminal screws.
- If the switch is indeed faulty, carefully loosen the terminal screws and remove the circuit wires from the old switch. Take note of how the wires are connected.
- Install a new switch by attaching the circuit wires to the corresponding terminals. Ensure that the wires are connected correctly and securely.
- Tuck the switch wires back into the electrical box and screw the new switch into place.
- Once the switch is secure, screw on the switch plate and turn the circuit breaker back on.
- Test the switch by flipping the toggle lever to the on and off position to ensure the light fixture is working properly.
If you are uncomfortable performing electrical repairs or unsure about any of the steps, it is always best to contact a professional electrician for assistance.

Realign the wall plate and screw into place
Before realigning the wall plate, it is important to follow the necessary safety precautions. Ensure that you have de-energised the circuit by opening the breaker responsible and verifying that there is no power running through the circuit. This is crucial for your safety.
Once safety measures have been addressed, you can proceed with realigning the wall plate. Start by identifying the type of wall plate and switch mechanism you are working with. This is important because different mechanisms may require specific approaches. For instance, if your wall plate has a fascia, you will need to remove it by gently prying around the edges with a flat-head screwdriver.
Now, you can focus on realigning the wall plate. One recommended approach is to keep the switch screws slightly loose. Place the wall plate over the switches and tighten the screws. This action will draw the wall plate and switches together, ensuring a snug fit.
However, it is important not to overtighten the screws as this can lead to cracking of the wall plate. Simply tighten the screws enough to hold the wall plate firmly in place.
Additionally, you can use a sacrificial two-gang cover as a jig. Drill holes above and below the rectangle hole to access the screws covered by the plate. This technique allows you to tighten the screws with full confidence that they are properly aligned.
Finally, after realigning the wall plate and screwing it into place, you can proceed to the next steps. Refit the fascia, energise the circuit, and test the switch to ensure it operates correctly.
