There are many types of DIP switches, and their working principles are basically the same. For example, the working principle of a six-digit DIP switch is mainly a combination of binary. Each digit is a combination of "0" and "1". There are a total of 64 kinds, which is a combination of 2 to the 6th power. The MCU makes relevant responses by identifying the combination.
Each DIP switch has a circuit board set in the multi-position BCD DIP switch. Before the 6 pins under each DIP switch output the corresponding BCD code, the BCD code will be generated through the printed circuit pattern.
In detail, for example, I want to use it to control the rotation time of the motor, how to achieve it. Take a YE DIP switch as an example. For example, if the DIP switch is 8, then the microcontroller will recognize it as 8. In this way, when the motor is operated, the microcontroller will be used to adjust the rotation speed or rotation time.

Those who are familiar with DIP switches should know that every high-quality DIP switch must pass a series of strict tests, and then pass various tests by the Quality Inspection Department before it can officially enter the market. As one of the important electronic components, the DIP switch, although small in size, is particularly important for intelligent machines. The quality of the DIP switch directly determines the normal operation of the machine. Therefore, Guangdu Industrial Co., Ltd. has formulated a set of rigorous testing and inspection procedures.

A high-quality DIP switch needs to meet the following requirements: First, the DIP switch itself needs to have a certain degree of chemical resistance, high temperature resistance, corrosion resistance, water resistance and environmental protection requirements, so as to avoid unnecessary occurrences during use. Loss and failure. Second, the materials must be real, not cutting corners or using inferior materials. The YE and KE series of DIP switches under Guangdu Industrial Co., Ltd., the upper cover and body are made of high temperature material (PPS) that meets the UL94V-0 fire rating, and the PA46 used on the push button also meets the UL94V-0 fire rating. High temperature materials. The fixed contacts and the movable contacts are all gold-plated copper alloy; even if it is attached to the film, it is also a high-temperature resistant film! Absolutely real.
