Double-sided adhesive on the membrane switch industry, perfect bonding effect
Overview of membrane switches:
Membrane switch, also known as light touch keyboard, is a one-piece combination of flat and multi-layered sealing structure. It is a kind of light collecting, machine and electric integration that seals the key switch, panel, mark, symbol display and liner. The new electronic components are fundamental changes in the appearance of electronic products. They can replace the buttons of conventional discrete components and perform the tasks of the operating system more reliably.
The thickness of the plastic substrate is 0.25mm or less, which is called the film. It is mainly used as the panel layer of the membrane switch. The back surface is printed with various indication patterns and characters to indicate the operation area of ​​the corresponding key position. Depending on the size of the panel and the buttons, the material is thick, the driving force is increased, and the reaction is slow; the material is too thin, the hand feel is poor when touched, and the rebound is not obvious. The thickness is more than 0.25mm, which is called sheet metal. It is not suitable for stereo key forming. It can be used as an indicator plate for the buttonless operation area. It can also be used as a liner for the membrane switch to improve its hardness.
