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.
