This work involves simply replacing traditional wall switches with dimmers.
There are two common dimmer switches.
More expensive is all
Range dimmer or rheostat.
It has a rotary knob that provides a fully variable control from dim light to full brightness.
It usually has 600-watt capacity (
The amount is stamped on the equipment)
This is enough for a typical living room lighting circuit.
The other type is the high/low dimmer.
Unlike the traditional wall switch, which has a lower price, there is a toggle switch instead of a knob.
The capacity of the high/low dimmer is usually only 300 watts, providing only two levels of brightness: 30% of full and about full.
However, in a complete
Range dimmer is not required, high/low dimmer is an economical alternative.
There\'s one for both types.
Rod design, the kind chosen when there is only one switch to control the fixture. Full-
Range dimmer is also available with three-
Method Design for a fixture controlled by two switches. Three-
The way in which the dimmer is made so that only one of the two existing switches is replaced;
Therefore, the light controlled by this switching circuit can be operated from two positions, but can only be darkened from one position.
To install the dimmer by replacing the existing wall switch, in most cases all you need is a screwdriver
Clamp and voltage tester (
A cheap device consisting of a small bulb with two wire probes available in hardware stores).
First ensure that the tester is working properly.
To do this, simply plug the probe into the slot where you know the effective wall socket;
The light bulb lights up if the tester is working.
Next, turn off the power supply of the circuit containing the switch by tripping the circuit breaker or removing the fuse of the control circuit breaker.
After that, try to operate the switch to make sure the light does not work (
This will indicate that the power is still on).
Then unscrew the cover plate of the switch from the wall.
Avoid contact with any metal, either on the switch itself or on the outgoing box on the wall, until you can use the voltage tester, as mentioned earlier.
Under the plate, find and release the two screws that hold the switch to the outlet box.
Gently pull the switch out of the box to reveal the connected wires;
Avoid contact with the wiring or terminal screws on the side.
Single-
The pole switch contains two brass terminal screws; three-
The Way switch contains three screws.
The ground wire of these two new models also has a small green terminal screw.
If there are four screws, the switch is four-
Design in a way used with two or three
Provides switches for additional control points.
These are not dimmers;
Replace one of the three
Instead, switch the way.
Terminal screws are not included in other switches.
The wiring enters the switch body through the hole at the back.
Most switches have holes and screws, but the wiring is connected only by one or the other.
Touch one probe of the tester to the metal outlet box, and the other probe touches each terminal screw or hole in turn.
If the outlet box is plastic and not metal, Please touch a probe of any bare copper wire (
These are ground lines)
In the box, when touching another probe to the terminal in turn.
If the tester bulb lights up, the power supply still flows to the switch.
Don\'t continue until you can close it.
Take the switch off when you\'re sure it\'s safe.
If the switch is single-
Rod, just loosen the terminal screw and remove the wire;
Alternatively, if the wire enters the terminal hole, insert the tip of the screwdriver into the slot near each hole so that the wire can be pulled out.
If the switch is three-
Way, place the masking tape on the wire connected to the dark
Color terminal screws or holes marked \"normal.
To install most dimmers, reconnect the wires to the terminal screws or slots that match the original switch. With single-
Pole switch, it makes no difference which wire is connected to which terminal. On a three-
Way switch, completely replace the line on the old switch with your shield function
Tape marking as a guide.
If so, connect the short-length bare copper wire or green insulated ground wire to the newly closed green terminal screw.
If there is a similar wire in the outlet box, please remove the plastic cover by unscrewing (
Called thread nut)
This connects them, wraps the end of the new wire around the already connected wire, and then replaces the cover.
If there is no bare or green
The insulated wire exists to securely connect the end of the new wire to any metal part of the outgoing box.
Some full-
Short wires have been connected to the dimmer.
To install this type, simply use the wire nut to connect the short line to the short line of the same color in the outlet box.
Push the connected switch into the outgoing box and fix it, be careful not to disturb the wiring.
Restore the power supply and test the switch.
Please connect the cover plate if it is valid.
Although most dimmers have a built-in
In electronic filters, they sometimes cause interference to the TV sets and radios plugged into the same circuit or operated nearby.
To solve this problem, move the TV or radio to another circuit and stay as far away as possible from the dimmer.
Get power if that doesn\'t work
Electrical line filters from electronic stores.
