(Summary description)Double opening means that there are 2 independent switches, which can control 2 lights separately. Both on and off are on the same switch. Dual control means that two groups of such cooperation can control one lamp without affecting each other. It can be turned on or off on any one of them. Single billing control is an ordinary switch, which can be used at the entrance of ordinary rooms, living rooms, kitchens, bathrooms, etc. Dual-opening and dual-controlling is not very practical in nature. It is recommended that single-opening and dual-controlling are used to combine the doorway of the bedroom and the bedside to form a set of openings, so that both the door and the bedside can control the light on and off, which is convenient, or there are ceiling lights and wall lights If you need to do 2 sets of switches, then use double-open and double-control, which can realize arbitrary control. Both dual-open dual-control and single-billing single control are relative terms. That is, there are several switches on the same panel, one switch is called single-open; two switches are called double-open and so on, and there are 3 switches and 4 switches. Dual control or single control refers to the controllable method on each switch. Whether a switch is single control or dual control, the direct way is to look at the number of binding posts on the back of the switch. There are two binding posts on a switch that are single control, that is, one in and one out; three binding posts are dual control, one in and two out, and one lamp can be controlled in multiple places. Single control means that a light has only one switch. Dual control means that a lamp has two switches (the same lamp can be controlled in different places, such as one door in the bedroom and one at the bedside, while controlling the bedroom light). But the dual control must be designed at the time of wiring. If you have a single-control line, you can’t achieve dual-control even if you buy a dual-control switch. However, dual-control switches can be used as single-controllers, which is a bit wasteful, because dual-control switches of the same specification are more expensive than single-controllers. Single-open, double-open, and three-open refer to several switches on a switch panel. Generally, double controls are used in the bedroom, and single controls are sufficient for the living room, kitchen, bathroom, balcony, aisle, and entrance. The dual control is more user-friendly, which greatly facilitates people who are inconvenient to walk. Of course, if the house is large, to facilitate the control, the use of dual controls according to the situation can have a convenient and fast effect.
