Waterproof Touch Keyboard Membrane Switches Graphic Overlays Moisture Proof

Waterproof Touch Keyboard Overlay Moisture Proof And Long Service Life

Membrane switch is an operating system that integrates button 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 contacts of the upper circuit are deformed downwards and are in contact with the plates of the lower circuit. After the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the circuit triggers a signal. Membrane switch has rigorous structure, beautiful appearance and good sealing performance. It has the characteristics of moisture resistance and long service life. Widely used in electronic communication, electronic measuring instruments, industrial control, medical equipment, automobile industry, smart toys, household appliances and other fields.
Membrane switch, also known as light-touch keyboard, adopts an integral sealing structure composed of flat multi-layers. The new type of electronic components is a fundamental change in the appearance and structure of electronic products. It can replace the keys of conventional discrete components and perform the tasks of the operating system more reliably.
