How to judge the quality of the membrane switch

There are many kinds of membrane switches, such as flat, convex, flexible, rigid, etc., then how to identify the quality of the membrane switch.

The manufacture of the membrane switch has a certain requirement for the panel, and the panel is also a decorative effect of the appearance of the product, so that a good membrane switch can be manufactured under the certain conditions that the film must conform to when manufacturing the panel. .

The preferred membrane switch has a good appearance, and the appearance is flat, the gloss is common, there is no mechanical operation, scratches, inclusions and stains. Secondly, the weather resistance is better, and it must be deformed, cracked, aged and discolored under certain natural environmental conditions. With good chemical resistance, the panel layer will have the ability to touch different chemicals, but for most common chemicals, such as alcohols, ethers, mineral oils, there must be a certain tolerance. .

Generally, the buttons on the membrane switch only use color to express the orientation, shape and size of the key body. In this way, the operator's vision can only be used to identify the accuracy of the operation, because there is no appropriate reaction information to indicate whether the finger is pressed according to the useful scale of the switch, thus affecting the speed of pride and operation of the whole machine monitoring. . The utility model relates to a membrane switch which is made to gently bulge the vital element and is slightly higher than the panel to form a three-dimensional shape, which is called a stereo key switch.
