Picture Example:

Membrane Switches integrated key function. It is composed of new electronic Keyboard operating system, indicator module and panel. Keyboard usually has six layers: Graphic Overlay composition, upper adhesive layer, upper circuit, isolation spacer layer, lower circuit and back adhesive layer. The contacts of the upper coil are down and in contact with the points of the lower coil. The circuit contact is released and bounces back, then the circuit breaks and the loop trigger the signal. The Membrane Switch panel has compact structure, beautiful appearance and good sealing performance.

It has the advantages of moisture-proof and long service life. It has been widely used in electronic communication, electronic measuring instruments, industrial control, medical equipment, automobile industry, intelligent toys, household appliances and other fields.

Working principle of graphic overlay membrane Switch

The basic working principle of the Membrane switch is when the key is not pressed down, the membrane switch is in the normally open state, its upper and lower contacts are disconnected, and the isolation layer will isolate the upper and lower lines.

When the key is pressed, the upper contact of the circuit deforms downward and merges with the lower circuit, causing the circuit to conduct electricity.

Connecting circuit signal of external connected instrument (substrate) to realize its corresponding function.

When the finger is released, the upper circuit that touches the low point will bounce back, then the circuit breaks and the loop trigger the signal.
