Definition Dual In – Line Low Profile DIP Switch

DIP switch (also called toggle switch, overclocking switch, address switch, dial switch, digital switch) is an address switch used for operation control. The 0/1 binary coding principle is used.
Introduction to DIP switch
Most of the DIP switches are used in the program control board to control the on/off of the performance circuit of the components. 그러므로, the DIP switch will also be called according to the industry sector: program switch, address switch.

Type of DIP switch
The DIP switch area has different concentrations: the 2.54mm pitch is divided into direct insertion type (DIP), surface mount type (SMD), piano key type, and angled type. There is also a dial switch 1.27mm pitch patch type

The principle of DIP switch
There are two pins on the upper and lower sides corresponding to each key of the DIP switch. Turn to the ON side, the upper and lower pins are connected; otherwise, they are disconnected. These four keys are independent and not related to each other. Such elements are mostly used for binary encoding.
It can be set to 1 for on; 0 for off, then:
0000
0001
0010
…
1110
1111
There are a total of 16 kinds of codes, which are used in a wide range of control. According to different products and designs, DIP switches are used in different ways.

The development history of DIP switch
In 1993, OMRON developed the first-generation key switch of the DIP switch, which evolved into a DIP switch.

The purpose of the DIP switch
Widely used in data processing, communication, remote control, anti-theft automatic alarm system, air shower, air-conditioning control panel, train model and other products that require manual programming.

Classification of DIP switches
As a kind of micro switch that needs to be operated manually, the DIP switch is widely used in many equipment products such as communication and security. Most DIP switches are in-line (DIP). Switch between the two states, and then form different states of 2 to the Nth power according to different bits to realize different functions. In fact, there are many kinds of subdivisions, and some specific series are introduced below.

1:1.27mm half-pitch type DIP switch
Its pitch is half that of a normal DIP switch, that is, Pitch 1.27mm. Main features Small size, occupying less space on the circuit board. Suitable for use in micro precision equipment. The specific parameters and dimensions are as follows:
