What you need to repair the switch
For work, you should purchase:
- Screwdriver, preferably indicator, to determine the presence of current. Also a simple flat one will do.
- Knife( installation or stationery).
- Insulating tape or heat shrink.
Step-by-step instruction for parsing the breaker. Step 1: turn off the electricity
To turn off the electricity, you should find in the house of the electrical panel, which contains the circuit breakers, protective shutdown devices or plugs. Automats and RCDs are switched off by lowering the lever, the plugs just need to be unscrewed. To determine the desired lever, use the indicator, checking each switch in turn for the presence of voltage in the wiring. Or, alternatively, turn off everything one by one and check again with the indicator if there is an electric current in the workplace( but check not only the switch, but the other device in the same circuit).This must be done for your safety.
Step 2: dismantling the switch box
To begin with, remove the keys on the switch. You can perform in two ways:
- Manually hold the protruding parts of the button, squeeze them to pull to yourself. In this case, pressing the guide grooves is carried out, which outputs a key from the axis, which leads to its easy removal.
- Using a screwdriver or a knife, press the key. To ensure that it, like in the previous example, was pulled out of the grooves, you should hold the key with your hand and pull it towards you.
After the key is removed, it is necessary to take a screwdriver and pull the center of the switch, pull it toward you. The decorative switch box is disassembled, and beneath it you will see two screws, which should also be removed with a screwdriver.
Important: do not lose the screws, because you can not find similar ones in everyday life, and buying new ones will take time and money.
Remove the switch from the receptacle.
Step 3: Test the
switch When inspecting the device, determine if it has any damage, such as melted contacts, which may cause a lack of light. It should be understood that then this device can not be repaired.
If there are no fused contacts inside the switch or other obvious damages, unscrew and re-tighten the screws holding the device wires and wiring. If any coatings or oxides are visible on the surface of the bolts and contacts, they should be removed with alcohol or other suitable solvent, and then wipe the elements dry. Often the problem is the poor and incomplete connection of electrical wires, and such actions can fix the problem.
Step 4: Insulation of wires and disconnection of the switch
In case the previous actions did not succeed, and the switch is working, it is necessary to insulate the cables with electrical tape, but it is necessary to make notes for connecting to the required connector.
Check the presence of current in the wires leading to the switch using the indicator screwdriver. There should not be any tension! Then unscrew the screws that secure the wires, and disconnect the latter. In the photo you can see which screws should be removed.
If the problem is not in the circuit breaker, but a circuit break has occurred somewhere earlier along the mainline, it will be detected by the special signaling devices described in the article http: //ogodom.ru/ obnaruzhenie-skryitoy-provodki-neskolko-sposobov-obnaruzheniya.html.
Types of switches
Switches are of several basic types. Despite the fact that the main principle of operation and disassembly of these devices is approximately the same, modern complex models can have additional contacts or indicators, which sometimes show different results than standard ones.
If the switch is not repairable and you decide to make a complete replacement of the device, you will need information on the types of modern instruments.
- Simple( consist of 1-2 keys).Most popular. Can be used to connect the light in different rooms. Externally they look like a button.
- Regulators - switches allow you to change the brightness of light in the house in a different color palette( from day to dusk).Differ on: manual and microcontrollers.
- Gusty. They have the appearance of a door bell and are connected to an impulse relay.
- Sensitive. They are divided into sound and regulatory. Sound react to clapping hands or voice, and regulating - to the console.
If you have to buy a new switch due to a malfunction of the old one, take with you an old sample for selection and replacement with a new model. Installation of the new device is also done from disassembly: extraction of keys, frames and plastic screws. Install the device in the opposite order of actions. Then connect the electricity on the shield and check the serviceability of the circuit breaker.
How to disassemble the switch is well shown in the video.
Now you know how to disassemble the light switch, so you can only wish success! Be careful!
