Dual-control home-installed switches are more common in home-installed circuits, and the wiring is relatively simple. Today we will take a look at the dual-control home improvement switch for everyone to explain how to connect the two control home improvement switch ?
Before introducing how to control the dual switch, let's first understand what is the dual switch?
At the same time, the switch has two normally-open and normally-closed contacts. In short, two switches can be used at the same time to control the on-off power of lamps and other electrical appliances. Usually used in the stairwells, of course, the bedroom entrance and bedside. This design can be very good to avoid the trouble of switching lights.
Before understanding the wiring diagram of the dual control switch, we are popularizing a common sense knowledge:
From the structure of the switch, "link" refers to a moving contact or a movable contact knife, "control" refers to a stationary contact, and single-link dual control may also be referred to as a "single-pole double-throw" switch. "Pole" and "Link" indicate the number of movable knives. Usually we will use the "pole" when describing the linkage between the switch and the switch. For example, there are 4 buttons on the concealed panel switch, but four single switches. There is no connection between them, so we call four single-switch but power commonly used three-phase air switch, because each phase has the same share of the same contact, so we call three-pole switch.
How to double switch?
On the three terminals of the switch, the moving contact is connected to the red line, and the two points of entry are connected to the fire line. Another switch, two static contacts electrically connect the two outgoing lines from the previous switch, and the moving contact appears on the zero line. Lamps. Some people often connect the two moving contacts of a switch to a loop, and the zero line static contacts appear on the fixture. This way is wrong and not standardized. Found to promptly get rid of.
