Wiring diagram of three-control Yi Deng switch
Install a 220V relay (two groups of dynamic closing and two groups of switching) in the dual-control switch. The principle of contact connection is shown in the following figure. The wire package is connected to 220V through a switch, which can be a double-control switch, a single-pole switch or a self-locking switch. Two double controls and one double knife two positions.
In home decoration projects, it is sometimes necessary to use three switches to control a lamp. For example, in a house with two rooms, one living room, one kitchen and one bathroom, the lighting of the living room needs to be controlled by three switches installed in the two rooms and the living room respectively.
At this time, if three double-control switches are used, this control cannot be realized; If one single control switch and two double control switches are used, although it is feasible in theory, it is inconvenient to use in practice. When the two dual-control switches are not connected, the single-control switch will lose its function, which is not desirable.
How to connect the three-way switch
1, everyone will want to use three switches to control the same light when the line is reformed. According to experts from Qijia. Com, the connection mode of three-control Yi Deng will be relatively complicated; Before wiring, we need to turn off the power supply and prepare two double-control switches and a crossing switch, of which the crossing switch should be installed in the middle position.
Next, let's prepare the wiring. First of all, we lead out the power supply live wire and connect it to the L end of the first double-control switch. Terminals L 1 and L2 of the first switch lead out two live wires, which are respectively connected to terminals L 1 and L3 of the second crossbar switch.
3. Terminal L 1 1 of the crossing switch is connected with terminal L32 by live wire, and terminal L 12 is connected with terminal L3 1 by live wire; Crossover switch L 1 1 connects the live wire outlet to the terminal of the third single-control switch L 1, and crossover switch L3 1 connects the live wire outlet to the terminal of the third double-control switch L2.
4. The L end of the third double-control switch is connected with the live wire lead-out wire and the live wire port of the lamp; The neutral led led led from the power cord is directly connected to the neutral port of the lamp. Finally, turn on the power supply, press the switch and check whether the line is connected properly. When connecting wires, everyone should connect the wires and switch terminals firmly. If the wires are virtually connected, it will easily lead to the problem of short circuit caused by wire burning.
The wiring diagram of the three-control Yi Deng switch and how to wire the three-open switch are all arranged here for you.
