For lighting, you need to connect a switch, so that you can control the light on and off. If there are many lights installed in the living room, then you must choose a three-way switch or a two-way switch, so that you can control all the lights. The lights are on and off, then, here we have to see how the three switches control the wiring of the two lights, and secondly, we must also know the classification of the switches.

How to wire three switches to control two lights
To achieve three controls, the head and tail still need to use a traditional two-way switch. In the middle of these two switches, a panel called a multi-control switch, or a midway switch, should be added. The movable contact is connected with a movable contact, which can be alternately connected with the stationary contacts L2 and L3 as the state of the switch button changes.
The multi-control switch in the middle has 2 movable contacts that act together. Press the button, and the 2 movable contacts can alternately connect with the respective 2 static contacts at the same time.
In this way, pressing any one of the three switch panels can change the on-off state of the entire circuit, so as to achieve the purpose of three switches controlling the on-off of a circuit at the same time, and the three switches have no difference in function.

Classification of switches
1. Classification according to use: wave switch, band switch, recording and playback switch, power switch, pre-selection switch, limit switch, control switch, transfer switch, isolation switch, travel switch, wall switch, intelligent fire switch, etc.
2. According to the structure classification: micro switch, rocker switch, toggle switch, toggle switch, push button switch, key switch, as well as fashionable membrane switches and point switches.
3. Classification according to contact type: The switch can be divided into three types: a-type contact, b-type contact and c-type contact according to the contact type. The contact type refers to the relationship between the operating condition and the contact state, "after the switch is operated (pressed), the contact is closed". It is necessary to select a switch with an appropriate contact type according to the application.
4. Classification according to the number of switches: single-control switch, double-control switch, multi-control switch, dimmer switch, speed control switch, splash-proof box, doorbell switch, induction switch, touch switch, remote control switch, smart switch, card access Switch, Yuba special switch.
For the method of how to connect two lights with three switches, the article has already written for you. If you want to use three switches to control the on and off of two lights, you can directly follow the method given above. In this way, the connection can be successful at one time, and you don't need to worry about this anymore. Similarly, you have learned what the classification of switches is, and you can look at the types first.
