Ask for advice on how to wire the three open dual control switch

Tools Required: Cone changer.

1. First, connect the yellow zero wire to the L1 of the switch and use it as the control line.

2. After that, connect the red live wire into L2 and tighten it with a screwdriver to prevent short circuit.

3. After that, the zero line coming out of the lamp is connected with the zero line of the switch.

4. After that, connect the live wire from the lamp to L11 together with the switch live wire.

5. After that, connect the light and the yellow zero wire of the light to L21, so that the three-open and dual-control switches are connected.

It is possible to share a single line of fire.

The three-open single-control switch is equivalent to the combination of three single-open single-control switches. Because there is no series connection inside the switch, it is necessary to separate jumpers to connect the common point L of the three switches, and the other three wiring ports are connected to the control lines of the three lamps respectively.

Generally, the three-open single-control switch has 6 wiring ports, and the three-open dual-control switch will have 9 wiring ports.

Materials required: wires, cross-shaped cones.

1. There are seven binding posts on the back of the three-open dual-control switch L1, L11, L12, L2, L21, L3 and L31.

2. Use four wires to connect L1 and L2 in a group, L1 and L3 in a group, L11 and L12 in a group, and L11 and L13 in series.

3. There are five lines on the wall, the red one is the fire line, the green one is the zero line, and the other three white lines are the control line.

4. Connect the live wire to L1, connect the neutral wire to L2, and connect the 3 control wires to L11, L12 and L13 respectively, then the switch installation is completed.

How to wire the three-open switch and connect the double control switch Hello dear, 1. First connect the yellow zero wire to the L1 of the switch and use it as the control line. 2. After that, connect the red live wire into L2 and tighten it with a screwdriver to prevent short circuit. 3. After that, the zero line coming out of the lamp is connected with the zero line of the switch.

4. After that, connect the waiting live wire to L11 together with the switch live wire. 5. After that, the lamp and the yellow zero line of the light are connected to L21, so that the three-open and double-control switches are connected to the three-control switch, which refers to the separate control of a device and equipment in many places, for example: three switches control the same lamp, that is, on the basis of dual control, add a double-pole double-throw switch in the middle of the connecting line of the two switches.

Dear, I'm glad to answer the question for you: how to connect the switch of double opening and three controls: 1. The switch is used to control the on/off of the socket power, and it can be wired according to the following methods:

Connect the L1 terminal of the switch (FireWire) to the L-terminal of the switch, connect the L1 terminal (FireWire outlet) of the switch to the Segai L-terminal (FireWire) of the two-pin socket, and connect the neutral wire to the N-terminal (neutral terminal) of the socket. 2. The switch is used to control the lamp, and the socket is not controlled by the switch. Wiring method:

Connect the live wire to the L terminal of the switch, connect the L1 terminal of the switch with a terminal block of the lamp head, connect the neutral wire to another terminal of the lamp head, and form a loop between the switch and the lamp. Then connect the live wire to the L terminal of the two-pin socket, and connect the neutral wire to the N terminal of the receptacle, and the two-prong socket becomes another circuit. 3. Standard wiring method of the socket:

There are three wiring holes in the three-hole socket, which are the L-live wire, N-zero wire, and E-ground wire, and the insulating skin at the end of the wire about 2 cm. I hope this helps, and if you have any questions, you can continue to ask me.

Three-open single-control switch panel: There are three switches on the panel, each switch has two binding posts, which can control one power.

Main method: use the L port of the switch to connect the power cord, L1 is connected to the lamps, and L2 is empty.

The incoming wire is connected to L1, L2, and L3 shorts, and the one that goes out is also a live wire, which is connected to L11, L21, and L31 respectively. There should be no neutral wire in the switch, and all these wires should be live wires (or control wires). There is only one power cord on the entire switch panel, and if you encounter two power cords, you can discard it - wrap it with insulating tape.

See the picture below: the light red is the power cord, and the three switches are connected in series.

1. First of all, you can see that there are three wiring holes on the back of the switch;

2. The general single control switch only has two wiring holes;

3. The three-hole switch is a single-open and double-control switch, and the width and height of the hole can be seen at the edge of the wiring hole, which is marked with "L1, L, L2" according to the method of "L inlet, L1 outlet, L2 connection";

4. After access, the switch shell is covered.
