1、 What is a membrane switch

Membrane switch, also known as light touch keyboard, adopts an integral sealing structure composed of planar multi-layer combination. It is used to connect key switches, panels and marks. Symbol display is a new type of electronic component integrating light, machinery and electricity, which is sealed by the backing plate. It is a fundamental change in the appearance structure of electronic products. It can replace the buttons of conventional discrete components and perform the tasks of the operating system more reliably.

2、 What is the structure of the membrane switch

The panel is the "jacket" of the whole membrane switch, and its main function is to mark and push buttons. The upper and lower circuits are the electrical components of membrane switches, which are also the "off" and "key" of switches, but their performance directly affects the performance of switching equipment. It is formed by printing a layer of conductive material on a thin film. The upper and lower circuits are responsible for the two shock characteristics required for the switch to close. The thickness is generally between 0.05-0.175mm, and the most common is 0.125mm pet.

3、 What are the advantages of membrane switches

1. It is a new type of man-machine interface, which integrates switch function and decorative function. The connection between the switch circuit and the whole machine can be completed by welding or plug-in.

2. The main type of film switch film switch panel is a kind of plastic (polycarbonate PC, polyester PET, etc.) film panel which is made of rigid or flexible printed circuit board as the substrate, installed with touch or no touch keys, and then covered with color decorative patterns.

3. The membrane switch has the advantages of good waterproof, dust-proof, oil-proof, harmful gas erosion proof, stable and reliable performance, light weight, small volume, long service life, convenient assembly and connection, washable panel without damage to characters, rich colors, and beautiful appearance. The use of membrane switches makes your products more contemporary
