By the panel, laminated rubber, the upper circuit, isolation layer, the lower circuit and the backing of the six parts of the membrane switch is composed of press down the membrane switch, the upper circuit contacts downward deformation, and the lower circuit of the pole plate contact conduction, finger release, the upper circuit contacts rebound back to the circuit break, the circuit triggers a signal. Membrane switch structure is rigorous, beautiful appearance, good sealing. It has the characteristics of moisture-proof and long service life. Widely used in electronic communications, electronic measurement instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances and other fields.

When the panel layer key is not pressed, the membrane switch is in the normal state, its upper and lower contacts are disconnected, and the isolation layer isolates the upper and lower circuits. The isolation layer isolates the upper and lower circuits; when the key of the panel layer is pressed, the contacts of the upper circuit are deformed downward and rejoin with the lower circuit to make the line conductive. When the key of the panel layer is pressed, the contact of the upper circuit is deformed downward, and the lower line is merged with the lower line to make the line conductive. After the conduction of the line to the external connection instrument (substrate) to signal, so as to achieve its corresponding functions; When the finger is released, the upper circuit contacts bounce back, the circuit is broken, and the circuit triggers a signal.

Product Advantage

Good water resistance (IP67)

KKG can process membrane switches that are waterproof. Using 3M300LSE + KKG's unique waterproofing process, the waterproof rating is IP67, enabling use in wet environments.

Membrane switches set switch keys, panel function text, mark, trademark, transparent window and display in one, the design of the panel layer, which can reflect the product function and unique colour conception fusion, distinctive.

Membrane switches are widely used in intelligent electronic measuring instruments, medical instruments, computer control, CNC machine tools, communication terminal equipment, all kinds of industrial and household electrical products (such as photocopiers, refrigerators, microwave ovens, electric fans, washing machines, video games, etc.).
