Hydropower installation is a top priority in home improvement. And with the increasing awareness of people's safety, the safety of hydropower is also of great concern. So how should the current hydropower installation be installed? The following decoration home decoration network Xiaobian for everyone to introduce the dual control switch wiring diagram , I hope to help everyone understand the hydropower installation!
1, the type of dual control switch
The dual control switch can be divided into single double control switch, double double control switch and triple double control switch because of the different switch buttons on the control panel. The wiring difficulty will increase according to the increase of the number of joints. At this time, a comprehensive dual control Switch wiring diagrams can help a lot, here are the principles, connections and wiring diagrams of these three dual-control switches.
2, what is the dual control switch
First of all, we first understand what is a dual control switch. The dual control switch refers to the separate control of two places in a certain device. For example, if it is a light, there is a light in the living room to control the living room. When you go to sleep in the bedroom. When you run to the living room to turn off the lights, you are tired. In the bedroom, you can also control a living room light by a switch. It is also common to control two motors in the factory. Therefore, dual-control is two keys on two panels that are not in place. A total of two power supplies can be controlled to achieve the same control in different places. Equipment (eg, lighting).
1, double dual control switch wiring diagram
The single dual-control switch is actually two single-pole double-throw switches connected in series and then connected to the circuit. Each single pole double throw switch has three terminals that are connected to two contacts and one knife.
2, double dual control switch principle
The definition of the dual dual control switch is similar to the definition of the single dual control switch. The only difference is that the dual connection is a switch of two buttons, and the single connection is only a switch of a button. So what is the dual dual control switch? In fact, it is very simple, that is, on one panel, two power devices are controlled by two buttons, that is, two switches control the two circuits.
3, double-connected dual-control switch wiring
First connect the middle terminal of a dual control switch to the live wire, then connect the middle terminal of the other dual control switch to the base (or the center tongue of the screw base), and then connect the return line, that is, use two green The wires are arbitrarily connected to the upper and lower terminals; the neutral wire is directly connected to the other contact of the lamp cap (or the thread of the screw cap) so that the connection is completed.
The above is the decoration house decoration network Xiaobian to bring you about the dual control switch wiring diagram , if you still want to understand the other knowledge of hydropower installation, please continue to pay attention to the decoration encyclopedia section!
