2. DIP switch principle - classification
There are many models of DIP switches. According to the pin position, there are points of DIP and SMD. According to the way of dialing, there are points for flat dialing and side dialing. According to the pitch of the feet, there are 2.54. The difference between mm and 1.27mm pitch is black, red and blue according to the color. There are two states and three states depending on the state. According to the number of bits, the normal number is 11 digits of 1-10 digits, 12 digits, and so on. In fact, there are many different subdivisions.
3. Dial switch principle
As a kind of micro switch that needs manual operation, the DIP switch is widely used in many equipments such as communication and security. There are two pins on the back side of each of the keys corresponding to the DIP switch. When the switch is turned to the ON side, the lower two pins are connected; otherwise, it is disconnected. These four keys are independent and not related to each other. Such components are mostly used for binary encoding.
If you set the encoding: turn on to 1; disconnect to 0, then:
0000
0001
0010
