Some friends have used many years of industrial light touch switch, but still do not know what the maximum current is, we have made the following explanation for these questions.
Contact resistance: in small current (100mA);
Insulation resistance: input 500V DC voltage for 1 minutes. Test according to the following contact method:
(1) between the contact terminals.
(2) between the pedestal and the foot.
Withstand voltage: input AC250V (50-60Hz) voltage 1 minutes induction current is 0.5mA, according to the following contact method test:
(1) the feet are between each other.
(2) between the feet and the outer shell.
Power: 250 0gf + 30gf;
Terminal strength: add 250gf strength test in any direction, the time is 2 minutes.
Test standard condition: temperature, humidity and air pressure are not specified:
(1) temperature 5 - 35 C
(2) humidity 45% - 85%
(3) the pressure is 80Kpa - 106Kpa
Use temperature: use at 30 +70 C temperature.
Weldability test: the top of the terminal is inserted into the 2mm depth of the tin bath, the temperature is 230 + 5 degrees, and the time is 3 + 0.5 seconds.
Weldability test: when the furnace is welded, the temperature is controlled at 260 + 5 centigrade, and the furnace passing time is 3 + 0.5 seconds.
Life test: no load: the frequency of the operator is 18-30 times per minute. Do 100 thousand non - load tests.
Cold tolerance test: placed in the temperature of 85 + 2 degrees C, after 96 hours of testing, then placed in the normal room for 1 hours to determine.
