Information

There are many kinds of membrane switches, such as flat ones, raised ones, flexible ones, rigid ones, etc. The manufacture of membrane switches has certain requirements for the panel, and the panel is a commercial appearance decoration and also has a protective effect, so In the manufacture of film panels, the film must meet certain conditions to make a good film switch.

 

The first thing is to have a good appearance, which should be flat and glossy. There are no appearance defects such as mechanical operation, scratches, inclusions and stains. Secondly, the weather resistance should be better, and it should be free from deformation, cracking, aging and discoloration under certain natural environmental conditions. With better 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 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, thus affecting the pride and operation of the whole machine monitoring speed. A kind of 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.
