There are many kinds of film switches, there are planar, there are convex, flexible, rigid, and so on, the manufacture of thin-film switches to the Panel has a certain requirements, panel it is the appearance of the decoration of merchandise also play a protective effect, so in the manufacture of the film panels to fit the necessary conditions can only create a good film switch.
The first appearance is good, the appearance is flat, luster common. There are no mechanical operation, scratches, inclusions and color spots, such as various exterior defects. Second, the weatherability should be better, in certain natural environment, not deformation, cracking, aging and discoloration. There is good chemical resistance, the panel will be able to urgently different chemicals, but for most common chemicals, such as alcohols, ether, mineral oil should have a certain tolerance.
In general, the buttons on the film switch only use color to express the orientation, shape and size of the key. In this way, the operator's vision can only be identified by the accuracy of the operation, because there is no proper reflection of the information to indicate that the finger is pressed on the switch's useful scale to make the switch action, thus affecting the machine monitoring of the pride and operation speed. A thin film switch which makes the switch key body lightly raised, slightly above the panel, constitutes a three-dimensional shape, called a three-dimensional key switch.
