How to wire the three open and dual control switch, and how to connect the three open and dual contr

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.

The method of connecting the triple open and dual control switches is: after L1, L2, L3 is connected to the live wire, it can be connected with the red light, yellow light and blue light, as well as L11, L21, L31 and L12.

First of all, L1, L2 and L3 should be connected, then connected with the live wire, then L11 should be connected with the red light, L21 should be connected with the yellow light, L31 should be connected with the blue light, and then the red light, the yellow light and one end of the blue light should be connected together, and then the double control should be connected after the single control, and then the L1 on the left and L1 on the right side should be connected, and then the L2 on the left side and the L12 on the right side should be connected.

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. If not, it can also be replaced with a double open.

Precautions for installation of three-open and dual-control switches

1. Before installation, the junction box should be cleaned to ensure that there are no impurities in the junction box, and the junction box should be checked for deformation or cracking. In addition, it is necessary to determine the height of the switch from the ground, which is usually required to be between meters, and if the interior is equipped with parapet wood panels, the distance from the top of the board is required to be more than 20 cm.

2. In the process of installing the socket panel, it is necessary to ensure that the panel is upright. If the line adopts the surface-mounted mode, the socket needs to be installed on the surface-mounted bottom box, and if it is a switch installed in the kitchen or bathroom, a waterproof cover should be installed to prevent water vapor from entering the switch and causing damage.

3. When installing, do not directly install it on the table or bed head, so as to avoid people accidentally touching the live body in the jack. There are two main ways to install the socket, one is the open installation, the other is the concealed installation, the height of the exposed socket needs to exceed the meter, and the height of the installation socket should be more than the meter.

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.

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 hole can be marked with "L1, L, L2" on the edge of the terminal hole, and it is wired according to the method of "L inlet, L1 outlet, L2 connection";

4. After access, close the switch shell and it is completed.

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.

Double-open single-control switch to control the wiring diagram of two lights.

Connect two lights, L12, L22 two holes are not wired.

Add two dual control wires between the two switches to complete the control requirements.

The connection method is as follows: the hole marked with L in the terminal of switch A is the common end, the live wire, and the double control wire is connected to both sides (the two holes are generally represented by L1 and L2).

The hole marked with L at the terminal of switch B is connected to the lamp head wire, and the two sides of the double control line are not divided into front and back (the two holes are generally represented by L1 and L2).

Add two dual control wires between the two switches to complete the control requirements.

Here's how to connect. The hole marked with L in the terminal of switch A is the common end, the live wire, and the dual control wire is connected to both sides (the two holes are generally represented), and the hole marked with L in the terminal of switch B is connected to the lamp head wire, and the two sides of the double control wire are not divided into positive and negative (the two holes are generally indicated).

Prepare two single-gang switches with L, L1, L2 terminal holes, and the wiring method is as follows: the live wire and the neutral wire of the bulb are connected to the common point L of the two switches respectively, and then connect the L1 and L1, L2 and L2 of the two switches, and the cross connection can also be. That's it.
