There are cases when a person faces the need to replace the switch or with its installation. To do this, it is better to call a specialist, but you can cope with yourself, remembering that all switches are put in the rupture of the wire (usually phase). The easiest way is to connect the switch with one key. Consider how it is done.
How to connect a single key switch - Design
Switch is a mechanical device designed to turn off the lighting devices. To begin, to further work easier to work, we will analyze the switch for hidden wiring and see what it consists of:
- on top of the device there is a rectangular plate - this is a switch key. It is not difficult to take it out, going with something sharp. In the same way, remove the plastic case;
- before you, the working knot with contacts, push-button drive, fastening paws, combined with a metal plate.
Now that you have familiarized yourself with the internal content of the switch, go to its installation.
How to connect a switch with one key - a simple option
Suppose you need to replace the faulty switch - that is, the place for mounting is designated. Prepare: screwdriver, indicator, pliers, new switch.
How to dismantle the switch with one key
- Turn off the packet (traffic jams, automata).
- Disassemble the old switch: Picture a thin screwdriver and remove it.
- Remove the 2 fastening screws and disconnect it from the device. You see 4 screws, two are contact (wired) and two - for spacer device.
To note: one contact comes (phase), the second - exhausted, the phase goes onto the light bulb.
- Remove the contact screws, free the wires and remove the switch body.
How to connect a new key with one key
Put the switch in the reverse order: first the case, then fasten the wire screws and install the plastic frame and key. Read more:
- clean the wires. Enter the phase wire first between the clamping plates, then the outgoing, and tighten the screws;
- loosen the slots of the spacer device, insert the switch to the opposite and tighten the screws;
- put the frame and secure it with diagonal screws. Insert the key and click on it (pre-turning on the automatic protection). Light burns, the case is done.
How to connect a switch with one key - a complicated option
Install the switch if the mounting place is not provided for it, a little more complicated. We will analyze the principle of connection at which the lighting device is used, switch, junction box and open type of wiring.
- Select the location for the switch and run the cable channel to the lighting device from the junction box.
Reference: Cable Cable is a box for protecting wires from different types of influences.
- Take a branch on the switch and place the wires into the cable channel.
- In the distribution box of the wire, work out, and through the terminal connectors, secure each other. In this case, the phase wire (it can be of any color, but not blue and yellow-green) skip through the switch.
Help: The wire section should be at least 0.75 square meters. mm.
- Connect three wires: zero (blue), protective (yellow-green) and phase to the lampshar. Turn on the electricity and check the operation of the switch. For clarity, see the drawing.
As you understand, connect a single-block switch is easy, the main rule is to de-energize the apartment and make installation according to the scheme.
