Tact switch performance test details

Tact switch we all know that there are many parameters, these parameters we how to test it, for example, the service life need to use the machine to test, the humidity resistance needs to be tested in a specific environment, etc., test these parameters we need to test a few more by sampling and then come up with a considerable data, according to this data to determine what the parameters of these tact switches, usually what we Usually what we call tact switch is the tact switch parameter.

In fact, we have to pay more attention to his performance when using the tact switch, to avoid improper use caused by damage, and we have to look carefully, because it has a variety of performance, and these different performance issues directly affect the normal use of people, if the performance of the switch itself is relatively good, then it proves that it can be widely used in other areas can continue to use, if it is not good performance then there will be a lot of problems. If the performance of the switch itself is not good, then there will be a lot of disadvantages, we just need to avoid these switches when buying. So how can we test the performance of tact switch? Here we will take a look.

The first thing to test is its drought resistance, there are many such tests, we can choose one of the simplest, in the test only need to soak the soldering foot into the tin pool can be, the test temperature should have a certain guarantee, preferably in the 225 degrees to 235 degrees between, if lower or higher than this temperature is not good, will also affect the final test results, the test time in 2.5 seconds to 3.5 seconds. 2.5 seconds to 3.5 seconds, this time is more accurate, so in the test must be strictly in accordance with this standard to carry out the test, can not be soaked too long or too short, so that the final test results will be biased, after the test we will find that more than 80% of the soldering feet are covered with tin, which proves that its quality is better, the product is also more formal, people use it. This proves that the quality is good, the product is also more formal, people will not produce too much danger when using it.

The second need to do is the drought resistance test, this test on the temperature of the test is very high, need to maintain the temperature between 255 to 265, in 4 seconds or 6 seconds between the need to maintain such a temperature all the time, this is the most perfect experiment, the final results of the experiment is also we need to pay attention to, because we are doing the drought resistance test, if the switch is deformed in the process of the test, then the switch is not particularly drought-resistant. Proof that its drought resistance is not particularly good, the performance is not good, but in the test did not appear in these cases, which shows that its quality is very good, but also very worthy of people to use.

The last thing we need to do is the cold resistance test, we need to do this test in cold conditions, preferably at -17 degrees to -23 degrees when doing this test, the time to keep in about four days, wait four days and then place it in a normal environment, wait 30 minutes and then test, so that the results of the test is the most correct, but also the most perfect. The results of these tests need to be carried out under the degree of accuracy, if there are problems with the accuracy, then the final results will be different, which is a problem that requires attention, if you want to do a good job of these tests, you need to familiarize yourself with the process of experimentation and the use of tools.
