Many friends want to test the performance of the touch switch they bought after they bought it, so how should they test it? Let's give you a detailed introduction.
Correct Method for Testing the Performance of Touch Switch
1. Testing of High Temperature Resistance of Light Touch Switches
Operating method: The product is stored for 2 - 3 minutes at 280 (+30 (?) C. The handle and resistance of the product are tested after heat dissipation.
Test results: Switch resistance, resilience, shape, etc. There is no damage to the switch.
2. Welding resistance test of light touch switch
Operating method: The temperature of soldering tin is controlled at 260 5 C, the holding time of over-furnace welding is 5 1 second, the temperature of hand welding is controlled at 350 30 C and the time is 3 0.5 seconds, but abnormal pressure can not be exerted on
The test results show that there is no distortion of the light touch switch, which proves that the light touch switch can meet the needs of various electrical appliances.
3. Test of Cold Resistance of Light Touch Switch
Operating method: Place it in the temperature environment of minus 20 3 for 4 days, then put it in the normal environment, and test it after 30 minutes.
The test results show that the contact resistance and insulation resistance of the switch are all within the standard range, and there is no indication that the performance of the switch is damaged. This proves that the light touch switch has better cold resistance.
4. Weldability test of light touch switch
Operating method: The welding foot of the light touch switch is soaked into the tin pool about 2 mm deep, and the test temperature is about 230 5 and the holding time is 3 0.5 seconds.
The test results show that more than 80% of the foam solder foot of the touch switch will be covered by tin, which proves that the quality of the touch switch is better.
