There are many types of Waterproof and dustproof membrane switches, including flat ones, raised ones, flexible ones, rigid ones, etc. The manufacture of waterproof and dustproof membrane switches has certain requirements for the panels, and the panels are also commodity-appearing decorations. In order to achieve the protective effect, the membrane must meet certain conditions when manufacturing the Waterproof and dustproof membrane switch to make a good membrane switch.
The first thing is to have a good appearance, and the appearance should be flat and glossy. There are no appearance defects such as mechanical operation, scratches, inclusions and stains. Secondly, the waterproof and dustproof membrane switch must have better weather resistance, and it must not deform, crack, age, or change color under certain natural environmental conditions. With good chemical resistance, the panel layer will have different chemicals, but for most common chemicals, such as alcohols, ethers, and mineral oils, it should have certain resistance.
Generally, the buttons on the Waterproof and dustproof membrane switch only use colors to express the orientation, shape and size of the key body. In this way, the accuracy of the operation can only be recognized by the operator’s vision, because there is no appropriate reflection information indicating whether the finger is pressed on the useful scale of the switch to make the switch action, so it affects the pride and operation of the whole machine monitoring. speed. A kind of Waterproof and dustproof membrane switch that makes the key body of the switch slightly protrude slightly higher than the panel to form a three-dimensional shape, called a three-dimensional key switch.
