The burn-in test of industrial switches generally refers to the continuous operation of products at full load for a long time. Generally 24 hours or 48 hours, of course, can be 1 hour or 0 hours, depending on the pursuit of quality and cost requirements. Burn-in test, also known as the oven or burner, is to test it harshly or "try to burn it" means, and the industrial switch burn-in test has a good reference standard in practical use.

  Most of the industrial switches just coming out of the production line have the complete function they were designed for and can be put into use directly, but why do they need to do aging test? Product quality theory tells us that most product failures occur in the early stage and the late stage. The late stage is the normal life of the product and cannot be controlled, but the early stage can be controlled. That is to do a thorough aging test of the product before it is put into the hands of the user, so as to kill the problem inside the factory. The regular manufacturers do this, but the counterfeit factories generally do not do aging testing, or leave the aging testing to the user. So we still often buy products that don't last long after we get them. In fact, this is the result of failing the aging test. Because users claim part of the work of the shanzhai factory, the shanzhai products are generally much cheaper.

  Of course, lucky customers sometimes get knockoffs that last a long time, and product quality theory goes like this: "If a product works for one day without breaking, it's probably going to work for a year without breaking." So if you buy a product and use it for a few days without breaking, it's probably going to stick with you for years, and that's what the aging test has shown.
