How to test the performance of the touch switch?

Time:2022/7/23Author:adminClick: 1123
Light touch switch is an electronic switch, belonging to electronic components. Touch the switch, as the name suggests, it is a kind of switch that we can turn on with a slight click, and turn off immediately when we release our hand. Its working principle is affected by the elastic principle of metal

1、 Welding resistance test:

1. Weldability test:

Methods: soak the welding foot into the tin pool about 2mm deep, the test temperature is about 230 ± 5 ℃, and the holding time is 3 ± 0.5 seconds.

Result: more than 80% of the soaked solder legs will be covered with tin.

2. Welding resistance test:

Methods: the temperature of soldering tin in the welding furnace is controlled at 260 ± 5 ℃, and the temperature of soldering tin in the furnace is maintained at 5 ± 1s at the time (substrate)

During manual welding, the temperature shall be controlled at 350 ± 30 ℃, and the time shall be 3 ± 0.5 seconds, but abnormal pressure shall not be applied to the welding foot.

Result: the switch has no deformation and can meet the electrical performance. Apply abnormal pressure, and this achievement will be scrapped.

2、 Cold resistance test:

Methods: put it in the environment of minus 20 ± 3 ℃ for 4 days, and then put it in the normal environment for 30 minutes.

Results: the touch resistance and insulation resistance are within the standard range, and there is no sign of switch performance damage.

3、 High temperature resistance test:

Methods: store the product at 280 ± 30 ℃ for 2-3 minutes, take it out, and test its feel and resistance after heat dissipation.

Achievements: resistance, acrylic rebound, shape, etc; There are no signs of damage. The switch performance is still intact.

4、 Humidity resistance test:

Methods: put it in the 90-95% RH environment at 40 ± 2 ℃ for 4 days, and then put it in the normal environment for 30 minutes.

Results: the touch resistance and insulation resistance are within the standard range, and there is no sign of switch performance damage.

5、 Temperature alternating experiment:

In different temperature environments, the test will be carried out after five cycles and then placed in the normal environment for 30 minutes
