Moisture resistance test method: Put it in 40 + 2 C 90 - 95% RH environment for 4 days, then put it in normal environment, and test it after 30 minutes.
Test Standard: Contact resistance and insulation resistance are all within the standard range, and there is no indication that the switch performance is damaged.
Cold-resistant test method: put in the temperature environment of minus 20 3 for 4 days, then put in the normal environment, and test after 30 minutes.
Test Standard: Contact resistance and insulation resistance are all within the standard range, and there is no indication that the switch performance is damaged.
High temperature resistance test method: under the temperature of 280 30 C, the product will be stored for 2 - 3 minutes and taken out. After heat dissipation, the handle and resistance of the product will be tested.
Test criteria: Resistance, resilience, shape, etc. There is no sign of damage to the light touch switch. The performance of the switch is as good as before. The soft rubber light touch switch is supplied.
Weldability test method: The welding foot is soaked into a tin pool about 2 mm deep, and the test temperature is about 230 5 C, and the holding time is 3 0.5 seconds.
Test Standard: More than 80% of the solder foot will be covered by tin.
Welding resistance test mode: the temperature of solder in the furnace is controlled at 260. 5 seconds, while the time of over-furnace soldering is maintained at 5. 1 seconds, the temperature is controlled at 350. 30 and the time is 3 0. 5 seconds, but abnormal pressure can not be applied to the welding
Test Standard: The switch has no deformation and can satisfy the performance of electrical appliances. The result of applying abnormal pressure is invalid.
The use of light touch switch with lamp is more and more popular and widespread. The light touch switch with lamp has a certain sense of hand. The different strength of using time can achieve different effects. Especially when the intensity tolerance range of light touch switch is relatively small, its feel will be better. The eight advantages of light touch switch with lamp are the most prominent characteristics of light touch switch with lamp.
The precision of the shrapnel is also very important when the switch is touched lightly with a lamp. The function of the shrapnel in the switch is to control the switch lightly with a lamp. If a single shrapnel has problems, the switch can not be used normally.
The detection method of light touch switch with lamp is very simple. As long as it is touched or pressed lightly, it can observe the sense of Carlton when it is pressed and the sensitivity of reaction. Whether it is a large type light touch switch with lamp or a small type light touch switch with lamp, it can make people feel the simple operation and the light touch switch supply.
Many materials with light touch switch have the effect of dust-proof and electricity-insulating. They should be carefully maintained in daily use. People can start with light touch switch, which is the insulating material with light, to eliminate more hidden dangers of light touch switch. In daily maintenance and detection of light touch switch, we should pay attention to whether light touch switch becomes fragile and deteriorated because of time aging. Quality problems such as decreased sensitivity or cracking.
If there is abnormal operation of light touch switch, remember not to disassemble it without authorization. This is a very dangerous practice. There is no professional maintenance environment. Many high-end electrical products need to be opened in a dust-insulated environment, because the dust will have conductive effect, so the detection and maintenance of light touch must be in a special environment. Conduct.
Because of the high sensitivity of light touch switch, we should pay attention to not over-squeeze when pressing, because both the control button on the precision instrument and the simple button on it have the same principle. When using the light touch switch, the sensitivity of light touch switch itself will be reduced if the light touch switch is pressed or struck vigorously.
