What is the explosion-proof dual-control dual-control switch?
1. The so-called "bit", also known as "link", means that on a panel, there are several switch function modules. "One" means that there is a switch, and "two bits" means that there are two switches that can control two electrical devices separately.
2. The so-called "control", that is, a switch selectively controls several circuits. For example, a dual-control switch, the letters a, b represent the circuit, that is, the process of the switch is to turn on a disconnect b, or turn b off a process. The two lines will not be turned on at the same time, nor will they be disconnected at the same time. In the home, two dual-control switches can be used to control the function of an electric appliance in two places through a certain rule of a certain line, and this function is more widely used in lighting of living rooms and bedrooms.
Explosion-proof duplex and bipolar are two different meanings.
What is the explosion-proof dual-control dual-control switch?
Explosion-proof double switch has three contacts, such as 1, 2, 3, set 1 as a common point, then there are two states: 1-2 pass 1-3 break or 1-2 cut 1-3 pass. Triple switch has four contacts, such as 1, 2, 3, 4, set 1 as a common point, then there are three states: 1-2 pass other break, 1-3 break other break, 1-4 pass other break. Multipole analogy. Like selector switches and the like. The general lighting switch does not have a triple switch.
Explosion-proof two-pole switch is two sets of contacts, there are four contacts, such as 1,2,3,4, there are two states: 1-2 pass and 3-4 pass and 1-2 break and 3-4 break. Three-pole switch has six contacts, such as 1,2,3,4,5,6, there are only two states: 1-2 pass and 3-4 pass 5-6 also pass, the other state is 1- 2 broken and 3-4 broken 5-6 also broken. Multipole analogy. Like circuit breakers, they are called unipolar, bipolar, and tripolar. Can not say two triple.
