1. What is a membrane switch?

Membrane switch is an integrated button system, which combines panel decoration, function marking and operation buttons. It has the advantages of light volume, easy installation, simple circuit interface connection, long key life, rich panel color, and prominent function marking. Features, and have certain functions of waterproof, dustproof, and harmful gas erosion.

Membrane switch is an integrated button system, which combines panel decoration, function marking and operation buttons. It has the advantages of light volume, easy installation, simple circuit interface connection, long key life, rich panel color, and prominent function marking. Features, and have certain functions of waterproof, dustproof, and harmful gas erosion. With beautiful appearance, comfortable feel, convenient equipment, stable quality, high reliability, long service life, low cost, small size, light weight, good waterproof / fireproof / dustproof / wear-resistant / oil-proof, power consumption Small features, using imported PC, PET materials and double-sided adhesive, according to customer requirements with rich colors, patterns, text, set the panel flexible circuits, pins, sockets in one. It is bound to quickly replace traditional mechanical switches and is widely used in household appliances, office equipment, instruments, machine tools, medical equipment, mechanical and electrical products, industrial control, toys and other complete products.

2. What are the product classifications of membrane switches?
Its main products are: flat touch keyboard, flat feel keyboard, concave and convex stereo keyboard and high performance waterproof type, membrane switch with light emitting diode (LED) type, with display window (LCD) type.

3. What are the performance advantages of membrane switches?
● Features of the keyboard with EL backlight, suitable for working at night or in a relatively dark environment for a long time. It can clearly display text, patterns and keyboard for a long time.
● Features of the keyboard with light storage: It can absorb and store the light source on the keyboard with the help of natural light sources or brighter lights during the day, and emit light at night or in a dark environment.
● PCB combined with membrane switch keyboard features: extremely small resistance value, sensitive key response, uniform operating force, long life, no short circuit.

1.Graphic Overlay – PET/PC is usually the material of choice due to its superior chemical resistance and flex life . XINLEI can either digitally print, screen-print, or employ a combination of both methods to ensure you get the right colors, textures and finishes your design requires.

2.Overlay Adhesive – This adhesive layer bonds the graphic overlay to the top circuit layer, and is typically an acrylic adhesive. The material is same as the fourth layer. Only the thickness will be different according to the physical truth.

The raw materials are strictly inspected before putting them into warehouse. Each process has a dedicated inspector. Unqualified products are not allowed to enter the next process. After passing the inspection work of each products process and electrical performance test, 20% more products are inspected on the basis of 100% final inspection.
