Metal dome   button, it is a PET sheet containing a metal sheet, used as a switch on PCB or FPC circuit boards. It plays an important tactile switch between the user and the instrument. Compared with traditional silicone keys, metal dome keys have a better feel and longer life, and can indirectly improve the production efficiency of various types of switches using conductive films. The metal sheet on the metal dome button is located on the conductive part of the PCB board (mostly located above the golden fingers on the circuit board). When pressed, the center point of the metal dome is recessed and touches the circuit on the PCB, thereby forming a loop. When the current passes, the whole product can work normally. This is how the metal dome button works.   We already know quite a bit about the metal dome buttons in the membrane switch panel. However, there are several types of metal dome keys. Next, we will make a classification for everyone.   Classified by structure ...

  Problems faced by enterprises in the design of membrane switch panels:   (1) Some companies lack sufficient experience in designing membrane switches or membrane panels;   (2) Even if there is a team of designers in the company, the designers may not understand the production process of membrane switch panels;   (3) The company is not clear about what constitutes an appropriate design, and does not understand the optimal solution of the appearance design;   (4) Excellent appearance does not mean excellent usability, and it is difficult to strike a balance between demand and cost. ......   JRPanel has concentrated on making membrane switches and membrane panels for more than ten years, and we are willing to be one of the solutions to the problem:   providing appearance design services for membrane switch panels .   How Does JRPanel Help to Resolve These Problems:   JRPanel has a professional design team and a rigorous design process. At the ...

  Circuit boards typically rely on membrane switches to turn parts of the device off and on. There are two main membrane switches in use today on printed circuit boards. One is referred to as a tactile membrane switch, and the other is called a non-tactile membrane switch. Each switch performs a different function on the printed circuit board. Here is an overview of the differences between a tactile and a non-tactile membrane switch. Construction A tactile switch is a momentary switch designed to provide a tactile (physical) response when pressed to activate it. There is an overlay on top of the switch that sits above a metal dome inside the switch. The overlay has letters, symbols, and/or designs on it that you use to identify what happens. When a symbol on the overlay is pressed down, it pushes a metal dome down under the symbol, so it presses against a conductive footprint. The conductive footprint then connects to the silver printed circuit, and action happens within the device...

  In membrane switch fileds, there are 3 main materials being used in production, PVC, PC and PET. To help you choose the proper material for your product, we would like to introduce you the difference between PVC, PC and PET in membrane switch applications.   1. PVC    PVC  is also called polyvinyl chloride membrane, the full name is Polyvinylchlorid membrane. The top layer of this structure is lacquer, the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. The price of PVC membrane is low, and it has excellent chemical resistance and insulation function. It is used in sign panels, but not suitable for membrane switches and light touch panels. The global usage of PVC membrane ranks second among various synthetic materials.   2. PC    PC is also called polycarbonate membrane, the thinnest is 0.01mm thick, amorphous, odorless, non-toxic, high transparency and low fogging. Chemical resistance: Dilute acid...

  The membrane switch production process is closely linked to the screen printing process.  Membrane switches use screen printing as the main process method, one of the few independent screen printing products that can serve the high-tech field. Here are the advantages of silkscreen printing: (1) Not limited by the size and shape of the substrate (2) Strong anti-rotation performance (3) Soft layout and small pressure (4) Flexible printing methods (5) Strong coverage of ink layer (6) Strong adhesion (7) Suitable for various types of ink (8) Suitable for long-term display, the outdoor advertising is expressive Today, we are going to introduce the working principle of silk screenprinting and its distinguishing characteristics. Working Principle Screen printing is composed of five major elements, namely,  screen printing plate  , squeegee,  ink  , printing table and  substrate .  The basic principle of screen printing is to use the basic principle tha...

Since membrane switches are custom designed to meet specific applications, each product will have its own criteria to meet. JRPanel has used its more than 20 years of membrane switch experience to compile some of the most critical guidelines to designing and specifying our products. The use of these guidelines will help ensure that all aspects of product  design are considered as to maximize the aesthetic quality, reliability, and efficiency of the final product.  Genral Considerations Enviromental:   What temperature and humidity range will this product experience? What types of contaminants or chemicals will come into contact with  this product? Will this product be subjected to moisture and/or U.V. exposure?  Electrical:  How many contact points will there be? What type pinout or matrix will be used? (common bus, X-Y matrix) What closed loop resistance will be acceptable? Will electrostatic or EMI shielding be necessary?  Mechanical: Will tactile re...
