Principle, connection method and introduction of double-pole double-control switch

There are many kinds of switches, and there are many switches to choose from according to different usage scenarios and corresponding crowds, such as traditional wall switches and switch designs of some lamps and meters. The difference between them may be manifested in appearance or function, and they are both indispensable key components. So today's Bian Xiao example is about the introduction of double-pole double-control switch, that is, its connection method, principle and definition.

1. What is a double-pole double-control switch?

In fact, the double-pole double-throw switch is composed of two single-pole double-throw switches connected in parallel, and its connection mode is exactly the same as that of each single-pole double-throw switch.

The two knives are connected by insulating plastic, and then the handle is used. Each side of the double-pole double-throw switch is equivalent to a single-pole double-throw switch and can be used as two single-pole double-throw switches; Every two adjacent terminals on the same side of the double-pole double-throw switch are equivalent to a single-pole single-throw switch, which can be used as four single-pole single-throw switches. Double-pole double-throw switch has different functions, such as changing the direction of current or voltage, exchanging the position of electrical components and so on, because of the different connection modes of A', B', A and B.

Second, what is the principle of double control switch?

The so-called double-control switch principle is composed of two independent single-pole double-throw switches. At present, almost every brand and series of switches on the market have unipolar and bipolar switches. No matter which switch (K 1 or K2) is toggled, the state of the whole circuit will be switched (on and off), so that any switch can turn on or off the controlled lamp at any time. This is dual control. Similarly, the three-control switch means that one of the three switches in different positions can control a lamp at will, and its circuit is a little more complicated, using a double-pole switch.

Third, how to connect the double-pole double-control switch?

In fact, the double-pole double-throw switch is composed of two single-pole double-throw switches connected in parallel, and its connection mode is exactly the same as that of each single-pole double-throw switch.

The two knives are connected by insulating plastic, and then the handle is used. Each side of the double-pole double-throw switch is equivalent to a single-pole double-throw switch and can be used as two single-pole double-throw switches; Every two adjacent terminals on the same side of the double-pole double-throw switch are equivalent to a single-pole single-throw switch, which can be used as four single-pole single-throw switches. Double-pole double-throw switch due to a? Different connection modes of A, B', A and B will have different functions, such as changing the direction of current or voltage, exchanging the position of electrical components, etc.

As one of the representative styles of switch products, double-pole double-control switch is also widely used, and the product value can not be ignored. Then the above example is the knowledge that can help consumers buy excellent products and have great reference value for users' operation: the introduction of double-pole double-control switch, that is, its connection mode, principle and definition. From this we can know its function, usage and maintenance ideas.
