Most home lighting now uses dual-control switches. The so-called dual-control switch is a device that can be controlled by two places. It is generally used to control the aisle lights on the stairs, the main light of the living room, and the main light of the bedroom. Turn lights on the 1st floor and turn off the lights on the 2nd floor. Turn on the lights in the bedroom door and turn off the lights on the bedside, which is very user-friendly. So, dual-control switch as a daily use of very high frequency things, if it is broken and can not find a timely manner to master how to do it? Therefore, it is very necessary to understand how the dual control switch is connected to prepare for the need.
How to connect the dual control switch 1. The principle of the dual control switch
Before explaining to you how to get the dual control switch, first of all, let us talk about the principle of the dual control switch, and know the principle. When you connect the dual control switch, your heart will be even more bottomed out. In order to make everyone more clear and understandable, please see the following figure:
When the switch is connected to the L1 circuit at the same time or the L2 circuit is connected to the light at the same time, when a call to L1, a circuit to L2 does not pass, the light will not light, it will turn off the light, I say it should be very Do you understand it?
How to connect the dual control switch 1. Method and procedure
We introduce two dual-control switches and one illumination lamp separately. The dual-control switch terminals are generally marked with "L", "L1", and "L2". When the L terminal enters the line, L1 and L2 have one end connected to L, and after pressing the switch, the other end of L1 and L2 is connected to L.
The first step: we first peeled the skin with diagonal pliers, taking care not to leave too long a thread so as not to touch it.
The second step: we use the L of the left end switch as the input of the fire line, L1 and L2 of the two switches correspond to the wiring, and then connect the right switch L to one end of the lamp, and the other end of the lamp is connected to the neutral line.
The third step: After the cable is connected, attention must be paid to cover the ends of the lamp with insulation tape to prevent leakage.
Step 4: Finally, leave the FireWire and the zero wire connected to the plug to complete the wiring of the entire dual control switch. To facilitate the wiring, we can remember the circuit diagram of the dual control switch, so that the actual operation is very easy to wire
See here, you probably know how to get the dual control switch , but after all, electricity is a dangerous thing, so we must shut down the power gate when we operate, if you want to learn more, you can continue to pay attention This website, follow-up small series will continue to explain this kind of knowledge for everyone.
