High-end instruments and products.

Membrane switch is an operating system that integrates key functions, indicators and dashboards. It consists of four parts: panel, upper circuit, isolation layer and lower circuit. When the film switch is pressed, the contacts of the upper circuit deform downward and make contact with the board of the lower circuit. After the finger is released, the upper circuit contact springs back, the circuit is disconnected, and the circuit triggers the signal. Membrane switch structure, beautiful appearance, good air tightness. It has the characteristics of long service life. Widely used in electronic communication, electronic measuring instruments, industrial control, automotive industry, intelligent toys, household appliances and other fields.

The plastic substrate of 0.25mm and below is called film and is mainly used as the panel layer of film switch. Various indicative patterns and words are printed on the back, indicating the operation area corresponding to the open key position. Thickness selection should be based on the size of the panel and the button, thick material, tactile increase, slow response; Material is too thin, feel poor, rebound is not obvious. Thickness above 0.25mm is called sheet and is not suitable for 3d key forming. It can be used as an indicator panel for the keyless operation area and as a lining board for the film switch to improve its hardness.
