Rubber membrane switch

Rubber membrane switches are usually used in office equipment, hand-held instruments, industrial equipment, household appliances, and rubber can be made into various three-dimensional effects to make the membrane switch products more comprehensive decoration and performance attract the eyes.

Silver paste, carbon paste, FPC, As the circuit layer, PCB can be assembled with LED, EL backlight, LGF, Metal Dome and other accessories, and it can also be made into a waterproof and dustproof rubber membrane switch.

Membrane switch product introduction:

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 moisture-proof and long service life. It is widely used in electronic communications, electronic measuring instruments, industrial control, medical equipment, automotive industry, smart toys, household appliances and other fields.

Basic introduction

Membrane switch, also known as light touch keyboard, adopts a flat multi-layer combination integral sealing structure. It is an optical, mechanical, and electrical integration that seals key switches, panels, marks, symbol displays and gaskets together. New electronic components are fundamental changes to the appearance and structure of electronic products. They can replace the buttons of traditional discrete components and perform the tasks of the operating system more reliably.

Membrane switches have the advantages of good waterproof, dustproof, oil-proof, harmful gas erosion, stable and reliable performance, light weight, small size, long life, easy assembly, panel can be washed without damaging characters, rich colors, beautiful and generous. Use membrane switches to make your products more characteristic of the times. The main types of membrane switches The membrane switch panel is based on rigid or flexible printed circuit boards, equipped with hand-feeling or non-hand-feeling keys, and then coated with plastic (polycarbonate PC, polyester PET) and printed with colorful decorative patterns. Etc.) Electronic components with integrated switch function and decorative function composed of thin film panels are a new type of man-machine dialogue interface. The connection between the switch circuit and the whole machine can be welded or plugged.
