LED+membrane button switch

  • Description

The LED membrane switch is an operating system that integrates key functions, indicating elements, LED backlights and instrument panels.


Membrane switch is an operating system that integrates key functions, indicating elements and instrument panels. It consists of four parts: panel, upper circuit, isolation layer and lower circuit. When the membrane switch is pressed, the contact of the upper circuit deforms downwards and contacts the board of the lower circuit. After the finger is released, the upper circuit contact bounces back, the circuit is disconnected, and the circuit triggers the signal. The membrane switch has a rigorous structure, beautiful appearance and good air tightness. It has the characteristics of long service life. It is widely used in electronic communications, electronic measuring instruments, industrial control, automotive industry, smart toys, household appliances and other fields.


Plastic substrates of 0.25mm and below are called thin films, which are mainly used as the panel layer of membrane switches. Various indicative patterns and text are printed on the back to indicate the operating area corresponding to the switch key position. The choice of thickness depends on the size of the panel and the buttons. The material is thick, the touch is increased, and the response is slow; the material is too thin, it feels bad to the touch, and the rebound is not obvious. Thickness above 0.25mm is called sheet material and is not suitable for three-dimensional key forming. It can be used as an indicator panel for a keyless operation area, or as a lining board for a membrane switch to improve its hardness.
