1. Principle of dip switch - Introduction

The dip switch, also known as DIP switch, toggle switch, overclocking switch, address switch, toggle switch, digital switch, or finger switch, was developed by OMRON in Japan. It is an address switch used for operation and control. Simply put, it is a miniature switch that can be manually turned. It mainly uses the binary encoding principle of 0/1. The dip switch has become more widely used, and currently the most widely used one on the market is produced in Taiwan.

2. Principle of dip switch - classification

There are many models of dip switches, which can be divided into direct insertion (DIP) and surface mount (SMD) according to their pin positions. They can also be divided into flat dial and side dial according to the way they are turned. They can be divided into 2.54mm and 1.27mm pin spacing according to their pin spacing, and black, red, and blue according to their colors. According to the state, there are two states and three states. According to the number of digits, it is normal to have 11 digits such as 1-10 digits and 12 digits. In fact, there are many more types when subdivided.

3. Principle of dip switch

As a type of micro switch that requires manual operation, dip switches are widely used in many equipment products such as communication and security. There are two pins on the back of each key on the dip switch. When turned on, the two pins below are connected; Otherwise, disconnect. These four keys are independent and not related to each other. This type of component is commonly used for binary encoding.

If the code is set: Connect to 1; If the disconnection is 0, there are:

0000

0001

0010

……

one thousand one hundred and ten

one thousand one hundred and eleven

There are a total of 16 types of encoding

4. Principle of dip switch - Classification

Simply put, it is a miniature switch that can be manually operated, so there are also many commonly called finger switches. Some well-known brands include Taiwan Baiying, Yuanda, KE, etc., which have outstanding quality but relatively high prices. Dial switches are widely used in products that require manual programming, such as data processing, communication, remote control, anti-theft automatic alarm systems, air shower rooms, etc.
