How to screen light touch switch brand quality supplier
In dongguan, choosing a light touch switch premium brand requires the following options.
1. The handle problem of the switch: adhesion problem, falling off of the cover, light on the non-conductive problem, the high resistance, and the failure of the furnace card.We all know that the handle and key force of the switch are controlled by shrapnel.We often say that shrapnel shrapnel into phosphorus copper and stainless steel shrapnel, the current domestic manufacturers to cut the costs are large department choose phosphorus copper shrapnel, domestic phosphorus copper shrapnel high cost performance, it is also widely used.But the phosphor copper shrapnel after the furnace temperature will produce the transformation, the shrinkage is more serious, this causes the hand feeling bad.
Is that supplier will know how to be careful to distinguish mixed cases, XKB switch brands should be used in Taiwan, Japan's imports of raw materials such as stainless steel shrapnel, to ensure each key switch handle, make sure every life of not less than 100000 times the following switch.
2. The selection of PI film is a common problem in dongguan ultra-thin touch switch. Thin, light touch switches are commonly referred to as thin film switches.The thin switch needs the film to cooperate, so that the real thin.However, many films have poor temperature resistance and will fall off after the furnace.Our professional term said adhesion, in fact, the film viscosity and import PI film very good control of this, its adhesion is 400 g, very accord with switch to use, how too light often fall off, if too heavy will switch according to fixed, many manufacturers in order to select the cost savings to produce cheap PI film, switch is very easy to adhesion problems.The same is true with a light touch switch with a point, and if you use a homemade one then your problem will come.
