A one light dual control switch should wear several wires

Single-link and dual-control switch.

A minimum of 3 threads can be used. Once the dual control switch is turned on, there are two switches. Each switch has three wires.

A single-pole, double-control switch is actually two single-pole, double-throw switches.

A switch that connects the circuit in series. Each SPDT switch has three terminals.

There are two contacts and one electrode.

Specific connection method: connect the two contacts of two single-pole double-throw switches respectively, that is, the contact 1 of switch 1 is connected with the contact 1 of switch 2, and the contact 2 of switch 1 is connected with contact 2 of switch 2, and then the knives of two switches are connected to the sound of lights at both ends as both ends of the whole switch.

The switch with one light and two controls should wear three wires in advance. In the cassette at the door, connect the live wire and the live wire to the bedside switch, and then access the L hole of the bedside switch, and the two control wires are respectively connected to the L1L2 hole of the switch, and at the door, the control line of the lamp is connected to the L hole of the switch, and the two control wires can be connected to the L1L2 hole respectively.

One light dual control switch, that is, two switches control one light.

Wiring: Between the two switches, there are two wires. The wire sent to each switch is a wire, one of the switches sends the live wire, and the other switch sends the light control wire.

In total, there will be three wires in each switch box.

One light and two control switches should wear three wires to be correct.

<> this is the wiring diagram of one lamp and two controls, three wires should be routed between the two switches, and the future live wire should be connected to the new switch, and there are two control wires, a total of three wires.

Three. One is connected to L (live wire), the other two are connected to L1, and one is connected to L2

When the actual installation and wiring, as long as one switch has a live wire, there is a neutral wire in the lamp, a control line on the other switch, and two double control wires between the two switches.

The zero line goes directly to the lamp, and then all the way to a duplex switch, and then connects two wires to another duplex switch, and finally leads out of the live wire from this duplex switch to lead the lamp is a duplex single control lamp!

Three switches. 6 or 7 main switches.

One lamp double control switch, should wear several wires, like the solid line instrument lamp dual control of the purpose must achieve three lines to achieve one lamp double control.

That is, a wire needs to be pulled between the two switches, and the rest is normal.

Summary. Hello, wear 3 wires.

Hello, wear 3 wires.

One light and two control switches, the junction box of each switch should wear 3 wires, one of the switches is a live wire, two control cables; The other switch is a control cable that goes to the bulb and two control cables.

The principle is a combination of two independent SPDT switches. As long as the control wires of the two sets of SPDT switches are connected with wires separately, the live wire inlet is connected to one end of the common end, and the neutral wire inlet is connected to the load and then connected to the other end of the common end, so that the SPDT switches at both ends can control the on/off of the load respectively.

Specific connection method: 1. The two contacts of the two single-pole double-throw switches are connected respectively, that is, the contact 1 of the switch 1 is connected with the contact 1 of the switch 2, and the contact 2 of the switch 1 is connected with the contact 2 of the switch 2, and then the knives of the two switches are connected to the sound of the lights at both ends as the two ends of the whole switch.

Five wires are required.

On each side is a power cord and two control wires. Then add the ground and neutral wires. To put it simply, it is 2 switches L1 L2 docking, one switch L into the fire line, and the other switch L into the lamp head line, which is a single dual control, and a double dual control is 2 panels.

1. The so-called "bit", also known as "link", refers to several switch function modules on a panel. "One bit" means that there is a switch, and "two bit" means that there are two switches, which can control two electrical devices respectively.

2. The so-called "control" means that a switch selectively controls several circuits. For example, the double-control switch is represented by the letters A and B, that is, the process of switching is the process of turning on A to disconnect B, or to turn on B to disconnect A. Both lines are not turned on at the same time, nor are they disconnected at the same time.

In the family, two dual-control switches can be used to control an electrical appliance in two places through certain wiring rules, and this function is more widely used in the lighting of the living room and bedroom.

Dual-control connection method: enter one live wire to the dual control switch, then send out two live wires to another dual-control switch, out one live wire to the lamp, and connect the zero wire at the other end of the lamp.

<> this is a typical connection method of one lamp double control, between the two switches to be arranged in advance three wires, in the switch place, find out the live wire, connected to another switch (switch two) there, there, the live wire into the l hole of the switch, the other two control wires are connected at will. In the switch digging type one, the control line of the lamp is connected to the L hole of the switch, and the two control wires are connected at will.

Four wires are needed, two are used as incoming wires to divide the incoming wires into two zero fires, directly into the socket, from the socket live wire and a wire to the terminal in the middle of the double control, each terminal on both sides of the terminal is connected to a wire on both sides of the other double control terminal, the middle terminal is connected to the power supply of the lamp into the fire, and a zero wire is taken again from another place, if not, add one to the four wires.

The word switch is interpreted as on and off. Or is it an electronic component that can open a circuit, interrupt current, or allow it to flow to other circuits. The most common switches are human-operated electromechanical devices with one or more electronic contacts.

Contacts"Closed"(closed) indicates that the electronic contact is on, allowing the current to flow through; Switch"Open the way"(open) indicates that the electronic contact does not turn on to form an open circuit, and the current is not allowed to flow through.

The switch only needs to be connected to the live wire, the first switching power supply is connected to L, L1 and L2 are connected to L1 and L2 of the second switch, and the L of the second switch is connected to the live wire of the lamp. The zero line of the lamp can be solved directly to the zero line.

The dual control switch has three wiring ports: upper L1, middle L and lower L2. Two switches control the connection of one lamp:

The live wire enters the L port of the first (any) switch, and then connects the L1 port of the two switches to the L1 port, and L2 to the L2 port, and then leads out a control wire from the L port of the second switch to the lamp head, and then introduces the neutral wire into the lamp head.

A light and a dual-control switch are called double-connected switches. Two duplex switches form two places to control the same lamp line.
