Thin Film Switch IP65 4x4 Matrix 50VDC Light Touch Keyboard

Use of membrane switch conductive circuit: widely used in switch panels of household appliances, instrumentation, mechanical electronics and medical equipment, factory name/trademark OEM, etc., fundamentally changing the defects of aluminum panels and other traditional panel materials, becoming One of the most ideal new panels in modern times.

The characteristics of the film panel: It is a kind of word mark and trademark that integrates decoration and functionality in an international fashion in recent years. Print established graphics, text descriptions, transparent windows, etc. on flexible plastic materials such as PVC, PC, PET, etc., and paste different types of double-sided tape to make plastic products used for identification and protection. The film panel has beautiful appearance, clear pictures and texts, and good airtightness. It has the characteristics of waterproof, anti-deformation, anti-pollution, anti-high temperature and strong viscosity. Widely used in intelligent electronic measuring instruments, medical instruments, computer control, CNC machine tools, electronic weighing apparatus, post and telecommunications, copiers, refrigerators, microwave ovens, electric fans, washing machines, electronic game consoles and other industrial and household appliances products.

The film sticker uses different materials, which determine its price and performance. The biggest feature of the film panel made by the silk screen process is:
