A "DIP switch" can refer to a single switch or an entire set of switches. DIP switches are usually designed on printed circuit boards and used together with other electronic components. The main purpose is to adjust the characteristics of electronic equipment. DIP switch can be regarded as a substitute for jumper group. Its main advantage is that the switch is easier to switch state than jumper, and there is no short circuit that may be lost or dropped.
Since 1990, DIP switches are rarely used in consumer electronic products. The reasons include the trend of shrinking product size, the simplicity of setting product configuration through software menu, and the price reduction of non-volatile memory. However, DIP switches are often used in industrial products, mainly because they are cheap, easy to integrate with circuits, and can be set when power is off.
Extended data
Classification:
1, half pitch type
Its foot distance is half that of ordinary dip switch, that is, the distance1.27mm. Its main features are small size and less circuit board space. It is suitable for micro and precision equipment.
2. Inclined plane type
The foot distance is 2.54mm, and it adopts downward inclination and flat type, which belongs to two States. The maximum strength of each series of actuators is 800gF, and the shell and actuator are made of PBT and UL94V-0. Contacts and endpoints are all gold-plated, which has strong reliability. The working temperature is -40 to 85 degrees, which is suitable for industrial grade.
3. Inclined sliding type
The pitch between feet Pitch 2.54mm, and the sliding in-line switch belongs to two states. Compared with KG series, the strength of its actuator is only half that of KG series. The actuator is 4/6 nylon, UL94V-0, white; ; The cover is made of PPS, UL94V-0 and black. It is also a gold-plated contact with a temperature range of -40 to 85 degrees, which is suitable for industrial grade.
