Film switch is an operating system which integrates key function, indicator element and instrument panel. It consists of panel, upper circuit, isolation layer and lower circuit. Press the film switch, the upper circuit contact deformation downward, and the lower circuit plate contact conduction, finger release, the upper circuit contact bounce back, the circuit is disconnected, the loop triggers a signal. Thin film switch structure is rigorous, beautiful appearance, good sealing. With anti - moisture, long service life and so on. Widely used in electronic communications, electronic measuring instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances and other fields. Film switch, also known as the light touch keyboard, adopts the overall sealing structure composed of plane and multiple layers. It is a new electronic component integrating optical, mechanical and electrical, which seals the key switch, panel, mark, symbol display and lining board together.
It is a fundamental change in the appearance structure of electronic products. Film switch has good waterproof, dustproof, oil proof, harmful gas corrosion prevention, stable and reliable performance, light weight, small size, long life, convenient assembly, panel can be washed and the character is not damaged, rich color, beautiful and generous advantages. Use film switch to make your product more contemporary. Film switch panel is a kind of electronic component which is composed of rigid or flexible printed circuit board, installed with feel or no feel keys, and then covered with plastic (polycarbonate PC, polyester PET, etc.) film panel printed with colorful decorative patterns. It integrates switch function and decorative function. It is a new kind of human-computer dialogue interface. The connection between the switch circuit and the whole machine can be completed by welding or plugging.
