If the contact is not good, check if the contacts inside are loose. Including the tin point. When the door is closed, is it closed properly?

The emergence of an industrial technology is often the result of the hard work of many people or even several generations.

Technically speaking, it is very simple to replace the membrane of the keyboard.

Technically speaking, it is very simple to replace the membrane of the keyboard. You only need to use a screwdriver to remove all the screws on the back of the keyboard, and then open the back cover.

The membrane switch panel of the present invention is the key molding structure of the membrane panel, which can be combined with the corresponding control panel.

Membrane keys are the basic structure of \"key + membrane\", so the feel and characteristics of the keys depend on the design of the membrane keys.

Two common faults in microcomputer microwave ovens are mostly related to membrane switches or FPC printed circuits

Advantages: ① Strong processing adaptability, different textures can be pressed on its surface to improve the appearance of the material.

The secret of membrane switch principle The emergence of an industrial technology is often the result of the efforts of many people or even generations. The purpose of continuous research and deliberation is to bring people a more comfortable and convenient life. The birth of new industrial products is more subtle. They are integrated into people\'s daily life. You may not fully understand these products, but you will definitely encounter them in your life. If you know how they work, it can be helpful to solve some small problems. Here is a new type of industrial product, the editor will take you to understand its principle. ?? Membrane switch is an operating system that integrates key functions,

What are the uses (applications) of film panels Membrane switch and membrane panel are a new type of electronic complete product operating system that is popular in the world in recent years, which integrates decoration and functionality. It has been widely used in intelligent electronic measuring instruments, computer control of medical equipment, CNC machine tools,

Introduction of FPC membrane key switch Metaldomearray is a PET sheet with contacts (including metal shrapnel, also called dome), which is used as a switch on circuit boards such as PCB and FPC, and plays an important role between the user and the instrument. The role of the tactile switch. Compared with traditional silicone keys, membrane keys have better feel and longer life, which can indirectly improve the production efficiency of various types of switches using conductive films. The contacts on the membrane button are located on the conductive parts of the PCB (mostly above the gold fingers on the circuit board).

What is the difference between a membrane switch and a traditional switch? 1. Long service life: The working life of the membrane switch is dozens of times that of ordinary mechanical switches. The life of the membrane switch can reach more than 10,000 times, while the life of the traditional switch ranges from 100,000 to 200,000 times at most; 2. Small size and light weight: the total thickness of the membrane switch is generally between 1.0 and 1.5mm, which is only equivalent to The thickness of an ordinary aluminum panel 3. Good sealing;
