Description
DIP switches are widely used in overclocking of computer motherboards, FM matching of wireless communication, radio and television equipment, and computer software programming of automation equipment.
1. Mechanical characteristics:
1. Operating force: 800g Max
2. Push button stroke: 0.9mm
3. Operating temperature: -20℃～+70℃
4. Storage temperature: -40℃～+85℃
Second, electrical characteristics:
1. Electrical life: Each switch is tested under the voltage of 24VDC and the current of 25mA, and it can be toggled back and forth 2000 times.
2. The rated current of the switch infrequently switching: 100mA, withstand voltage 50VDC.
3. The rated current of the switch frequently switched: 25mA, withstanding voltage 24VDC.
4. Contact impedance: (a) the maximum initial value is 50mΩ, (b) the maximum value after the test is 100mΩ.
5. Insulation resistance: minimum 100MΩ, 500VDC.
6. Compressive strength: 500VAC/1 minute.
7. Interpolar capacitance: maximum 5pF.
8. Loop: single contact single selection
3. Welding and cleaning process:
1. During all operations, please make sure the switch is in the "off" position.
2. Reflow soldering: The high temperature of the reflow oven is 230°C and lasts up to 30 seconds.
3. Hand soldering: Use a 30-watt soldering iron to control the temperature at 608°F (320°C), and the soldering time is about 2 seconds.
4. Cleaning process: Ultrasonic cleaning can give better results. When using steam, the temperature should not exceed 125°F (51°C).
