Dip switch (also called DIP switch, Dip switch, overclocking switch, address switch, Dip switch, digital switch, Dip switch) is an address switch used to operate and control the switch, using a 0 / 1 binary coding principle.

1. Meaning

Dip switchs are mostly used for program control plate, and the performance circuit of control components is connected and disconnected. So the Dip switch will also be called according to the industry plate: program switch, address switch, and the most familiar Dip switch.

2. How it works

The Dip switch has two pins on the back of each key, dial to the ON side, the pins are turned on; otherwise. The four bonds are independent and are not related to each other. These components are mostly used for binary encoding.

It can be set to 1, disconnected to 0, then:

0000

0001

0010

……

1110

1111

There are 16 kinds of coding, used in a wide range of controls. According to different products and designs, the use of Dip switches in different ways.

3. Function

The main function of dialing switch is to realize the switch and selection of signal in the digital circuit. It can easily realize the input, output, control and other functions of digital signals. Common Dip switches have different specifications of 4,6,8 bits, 10 bits and other specifications, which can meet the needs of different applications, such as setting address, selecting functions and so on.

4. Types

● Half-spacing: its foot distance is half of the normal Dip switch, which is Pitch1.27mm. The main characteristics of small size occupy less space on the circuit board. Suitable for use in micro-precision equipment.

● DIP flat: the foot distance is 2.54mm, using the top dial straight plug (DIP), flat, belong to two states. The strength of the actuator is up to 800 gF in each series, and the shell and actuator are made of PBT and UL 94 V-0 material. Contact and ends are gilded, strong reliability. The operating temperature is from-40 to 85 degrees, suitable for industrial grade.

● DIP sliding type: foot spacing Pitch2.54mm, sliding straight plug type switch, belongs to two states. Compared with the KG series, its executive force is only half as powerful. The actuator is 4 / 6 Nylon, UL 94 V-0, White; the cover material is PPS, UL 94 V-0, Black. is also gold-plated contact, temperature range-40 to 85 degrees, suitable for industrial grade.

● DIP key type: foot spacing Pitch2.54mm, top dial straight insert (DIP), two states, key type. The bulge of the actuator is only 0.9mm. Gold-plated contact point, strong reliability. The actuator travel is only 0.9mm, the actuator and cover material are Nylon, UL 94 V-0. The temperature range is also suitable for industrial grade.

● DIP ultra-thin sliding type: foot spacing Pitch2.54mm, top dial straight plug type (DIP), two states, sliding type. Gold-plated contact point, strong reliability. The actuator and cover are made of 6TNylon, UL 94 V-0. The ultra-thin thickness is only 3.7mm, and the actuator thickness is only 0.6mm, which is suitable for use in precision instruments.

● DIP key convex type: foot spacing Pitch2.54mm, top dial straight plug type (DIP), two states, key type. The contact part is the gold-plated contact, which ensures high reliability through the self-cleaning structure of the action. Actuator material 4 / 6 Nylon, UL 94 V-0, convex type. Outer cover material: PPS, UL 94 V-0. Its width and thickness are 10.7mm, 9.5mm, which is larger than other series. Suitable for up and down operating equipment.

5. Advantage

● Real-time configuration: can be configured on the device without software or computer.

● Reliability: no electronic components vulnerable to environmental interference problems, high durability.

● Simple operation: set by physical dial, simple and intuitive operation.

6. Installation considerations

● About the external program: when inserting the external program, please follow the direction of the arrow of the external program. The insert load of the external program is as follows, each A7B-C unit is about 14.7N, and NRT-C is about 34.3N.

● About welding: When welding the wiring substrate, please note the following points. During the automatic welding, please weld within 30W, 350℃ and 3 seconds. When cleaning. Ditto, do not apply force to the terminal when welding and for 3 minutes. Otherwise, it will lead to poor conduction or movement. Please do not let the welding flux and alcohol enter the interior of the switch.

7. Usage considerations

● About the use place: do not use in places where gas (ammonia gas, chlorine gas, sulfur dioxide, etc.). Because do not have anti-dropping, therefore, do not use in dripping, dripping places, also do not stick in the hand of water, oil, especially in the dust flying place, please set a dust cover, and improve the dust treatment.

● About the storage place: in high temperature, high humidity environment and long-term storage at room temperature is easy to cause the terminal oxidation reaction, resulting in welding part failure. Please avoid high temperatures, high humidity environment storage, use it as soon as possible.

● About use: Do not touch the charging unit when power. Do not connect multiple power supplies on one switch. Will cause misoperation and short circuit of the circuit. If you want to modify the value setting, do not use wet fingers or stick oil on the hand, and operate the operation button when foreign body. If you want to remove surface dirt such as the molded resin shell, it is recommended to use alcohol. But be careful not to let alcohol penetrate inside. When removing the connection, please use a screwdriver to remove the upper and lower claws. Do not press the propulsion operating button. Falling may cause terminal deformation, damage to the printing substrate, and break the resin stuck claw used to connect the switch side, so be careful not to make it fall.

Conclusion

As the core configuration tool in the digital device, the Dip switch provides a direct and reliable way to adjust the operation mode and parameter options of the device. They play an indispensable role in the application field of electronic technology, providing basic support for the flexibility and adaptability of devices.
