Product Description

(1) Mechanical Properties

1> Operating Force: The operating force for a single-pole switch shall not exceed 8 N.
2> Key travel: 2 mm
3> Operating temperature: -25℃ to +70℃
4> Storage temperature: -40℃ to +85℃

 

(2) Electrical Characteristics)

1> Rated current for frequent switching: 25 mA, withstanding voltage of 24 VDC.
2> Rated current for switches that are not frequently toggled: 100 mA, withstanding voltage of 50 VDC.
3> Contact impedance: Initial value not greater than 50 mΩ; post-test value not greater than 118–132 mΩ.
4> Insulation resistance: not less than 100 MΩ, 500 VDC
5> Parasitic capacitance: not greater than 5 pF
6> Electrical Strength: It shall withstand an electrical strength test at a fundamental sinusoidal waveform, 50 Hz, 500 VAC for 1 minute, with no flickering or breakdown.
7> Circuit: Single-Contact Single-Selection: DS(S), DP(L)
8> Electrical life: The single-pole switch was tested at 24 VDC and 25 mA; after 2,000 actuations, it continues to operate normally.

 

(3) Welding and Cleaning Processes

1> During all operations, ensure the switch is in the “OFF” position.
2> Wave Soldering: Recommended soldering temperature is 464°F (240°C), with a maximum duration of five seconds.
3> Hand Soldering: Use a 30-watt soldering iron, maintain the temperature at 608°F (320°C), and keep the soldering time to approximately 2 seconds.
4> Before completing the solder repair: Please ensure the switch lever is in the “OFF” position (the default factory setting).
5> Cleaning process: Ultrasonic cleaning delivers superior results; when using steam, the temperature must not exceed 51°C.
