Information

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

quality PET circuit membrane switch

The high-quality PET circuit membrane switch must have a good appearance, flat appearance and common gloss. 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 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 a certain ability to withstand.

Generally, the buttons on the high-quality PET circuit 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, which affects the pride and operation of the whole machine monitoring. speed. A kind of PET circuit 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.
