Product overview

Membrane switch, also known as a light tactile keyboard, adopts an overall sealing structure composed of flat multi-layers. It is a kind of optical, mechanical, and electrical integration that seals the key switch, panel, mark, symbol display, and lining together. New electronic components are a fundamental change in the appearance and structure of electronic products. They can replace the buttons of conventional discrete components and perform operating system tasks more reliably.

Membrane switch are waterproof, dustproof, oil-proof, harmful gas corrosion resistant, stable and reliable performance, lightweight, small in size, long life, easy to assembly, and assembly, the panel can be washed without the characters being damaged, rich in colors, beautiful appearance, etc. advantage. Use membrane switches to make your products more contemporary. The main type of membrane switch is a membrane switch panel, which is made of a rigid or flexible printed circuit board as a base, installed with touch or non-touch buttons, and then covered with plastic (polycarbonate PC, polyester PET) printed with colorful decorative patterns. etc.) is an electronic component composed of a thin membrane switch that integrates switching functions and decorative functions. It is a new type of human-computer dialogue interface. The connection between the switch circuit and the whole machine can be accomplished by welding or plugging.

Flexible membrane switch

A flexible membrane switch is a typical form of membrane switch. This type of membrane switch is called flexible because the mask, isolation, and circuit layers of the membrane switch are all composed of flexible films of various properties.

The circuit layer of the flexible membrane switch uses polyester film (PET) with good electrical properties as the carrier of the switch circuit pattern. This layer is divided into feel elastic pieces and upper and lower circuits. Due to the properties of the polyester film, the membrane switch has good insulation, heat resistance, bending resistance, and high resilience.

The graphics of the switch circuit, including the connection of the switch and its lead wires, are printed with low-resistance, conductive paint cured under low-temperature conditions. Therefore, the entire membrane switch has a certain degree of flexibility and is not only suitable for use on planar bodies but can also be matched with curved bodies. The lead wire of the flexible membrane switch is integrated with the switch body itself. When making the connection of the group switch, it is gathered at a certain point of the membrane and extends outward according to the position specified by the design and the standard line spacing. As a soft, the sealed lead wire that can be bent at will is connected to the rear circuit of the whole machine.
