How big is the current in the light touch switch and what are the other parameters? Today we will introduce them to you. I hope you can understand these problems.
Contact resistance: at a small current (100mA);
Insulation Resistance: Input 500VDC voltage for 1 minute, test according to the following contact method:
(1) between contact terminals.
(2) between the rubber base body and the row foot.
Voltage withstand: Input AC 250V (50-60Hz) voltage 1 minute induction current is 0.5mA, according to the following contact method test:
(1) between the feet.
(2) between the feet and the shell.
Active power: 2500gf + 30gf;
Terminal strength: add 250gf force test in any direction for 2 minutes.
Test Standard State: Test temperature, humidity and air pressure in the absence of specified conditions as follows:
(1) Temperature 5-35 C
(2) Humidity 45%-85%.
(3) Pressure 80 Kpa-106 Kpa
Use temperature: in - 30 C + 70 C temperature.
Weldability test: The top of the terminal is put into the 2 mm deep soldering pool, the temperature is 230 5 and the time is 3 0.5 seconds.
Welding resistance test: the temperature of the welding furnace is controlled at 260, 5 C, and the overheating time is 3, 0.5 seconds.
Lifetime test: No load: Operator at 18-30 times per minute frequency. Do 100,000 load-free tests.
Cold-resistance test: Place it in the normal room for 1 hour after 96 hours of testing at 85. 2 C.
