When switch buttons are needed in the human-machine interface MMI, engineers will consider what type of components to use to complete the job. Among the many key products to choose from, planar or quasi-planar switches, small keyboards or touch keyboards have begun to replace traditional mechanical switches. Especially in the design of consumer electronic products that are very price-sensitive, membrane switches have even more obvious advantages due to their high cost performance.



The membrane switch is a control system that integrates button functions, appearance display, and instrument panel. Because of its rigorous structure, beautiful appearance, good sealing, waterproof and dustproof, and long button service life. It is widely used in electronic communication equipment, electronic measuring instruments, industrial control equipment, medical equipment, automobile industry, smart toys, household appliances and other fields.



Membrane switch technology was first introduced to China in the late 1990s. Taiwanese and Hong Kong businessmen set up factories in Shenzhen, Dongguan and Guangzhou in the Pearl River Delta for processing and production. As China's industrial technology becomes more and more mature, many foreign brands have set up OEM factories in China. Therefore, membrane switches also have a domestic consumer market. At the same time, a number of membrane switch manufacturers were also produced in Zhuhai and Nanjing.

Many people are asking which manufacturer of membrane switches is the best and ranks high? In fact, this statement is not very accurate, because everyone produces the same type of products, and technical and engineering personnel are highly mobile, which indirectly promotes the mutual circulation of membrane switch technology. Old factories have rich production experience, but the equipment is not necessarily the latest and the relative precision is poor. Large factories have many employees, but quality management may not be 100% good. Therefore, we can only look at a comprehensive comparison. Due to the high concentration of technical personnel and convenient material transportation in coastal areas, the comprehensive production level of membrane switches is relatively higher than that of inland factories.



Rechan Electronic Technology Co., Ltd. is a mature membrane switch manufacturer. Specializing in the production of high-quality flat touch membrane switches, convex button membrane switches, LED backlight membrane switches, waterproof membrane switches for medical equipment and other products. Especially for capacitive touch sensing membrane switches, PET and FPC flexible touch sensing switches, etc., our production technology dominates the industry and is at the top level. All types of electronic equipment manufacturers are welcome to come to the factory to discuss customization. kevin@rechan.com
 

"Counterpart" is described as a thriller spy drama full of twists and turns, shot in Berlin, Germany and Los Angeles, the United States. It tells the story of Howard Silk (JK Simmons) whose job in the play is to guard a door that leads to another parallel world. On the other side of the door is a completely different world, but there are people exactly like this world. Coincidentally, there was a very serious flu in that world before, which was highly contagious. It was very similar to our current COVID-19 epidemic. As a result, their technological development was slow, and they are still using push-button mobile phones.



If you are interested, you can search it out and watch it. It is indeed an excellent TV series. What was very surprising was that I actually saw products produced by our company in the drama! It’s the security code input device in the picture below.


The intermediate input device uses a metal casing, assembled with a PCB movement and a bulging button panel. The material used for the panel is XEV150 from British Autotex. The surface is frosted, feels very good, and can protect against ultraviolet rays.


The new model has been changed to a hidden LED light. When it is turned off, the LED light is not visible on the surface. It is only displayed when the LED is turned on.

The oval groove at the lower part is used for customers to assemble their own LOGO.

Membrane switches are different from traditional mechanical switches. Membrane switches do not have high requirements on the layout of the casing. There is no need to prepare holes for buttons on the casing, and they are easy to install. The surface of the membrane switch is a printed panel. The material can be PC or PET. It can be divided into frosted surface and smooth surface. It is commonly made of British Autotex material.

The membrane switch is beautifully printed, with a metal shrapnel in the middle. There are single or multi-layer silver paste circuits under the shrapnel. It has low resistance and a sensitive switch. The membrane switch button feels comfortable and has a long service life. There is double-sided tape on the bottom that is directly attached to the product casing, making installation easy.

Membrane switches are scratch-resistant, wear-resistant, waterproof, fireproof, dustproof, and resistant to harmful gases. It is widely used in household appliances, office equipment, instrumentation, machine tool equipment, medical equipment, mechanical and electrical products, industrial control equipment and electronic toys.

Rechan Electronic Technology Co., Ltd. is a manufacturer of membrane switches, touch buttons, and control panels. We have comprehensive innovative membrane switches, touch buttons, and control panel knowledge, professional technical team design, exquisite production technology, and advanced membrane switches, touch buttons, and control panel testing equipment.

2020 is a very sad year. Although it is not the end of the world, the new coronavirus has made us mentally exhausted and made us pay more attention to the health of the air! To this end, the American company Alen has developed a new and more intelligent touch switch air purifier. The control part adopts an acrylic panel with IMD technology and a capacitive induction trigger circuit, which makes it full of technology.





The control part of this air purifier uses an IMD acrylic panel and a translucent indicator window. When it is turned off or in hibernation, the entire surface is the same color, and no other key switches are visible. Only the position of the power button, logo and product model are displayed. Touch the power button to turn on the light and display all buttons.



The back of the panel uses a capacitive touch sensing circuit. Tear off the protective paper and stick it on the panel (there is 3M double-sided tape on the circuit board). The key positions are screen-printed with transparent sensing conductive oil, and commands can be issued by touching the panel keys with your fingers. The conductive oil transmits light and diffuses the LED light, making the light from the key position more uniform.


The back of the panel is equipped with a capacitive touch sensor switch FPC flexible circuit board.

Rechan Electronic Technology Co., Ltd. is a manufacturer of capacitive touch sensor control switch circuits and FPC flexible circuit boards. Professional customized production: membrane switches, touch buttons, control panels, FPC flexible circuit boards, capacitive touch sensor switch circuit boards, induction control touch screens, etc.

The company has an advanced technical team and many years of experience in membrane switch and touch switch design. Use high-quality PET or diffusion film and other raw materials to print transparent conductive oil, silver paste, carbon paste, UV, 3M glue and other inks. Attach it to a PC or PMMA acrylic panel, and plug the other end into the PCB circuit board with an FPC connector to form a capacitive touch sensor switch.
The PC acrylic panel on the surface of the capacitive touch sensor control switch has exquisite silk screen printing, clear buttons, highly transparent LED display window, and responsive buttons that can be reached at a touch. And the price is much lower than that of touch screens, which have replaced traditional mechanical switches in large numbers.

Touch switches are widely used in various industrial and household appliance fields such as intelligent electronic measuring instruments, medical instruments, computer control equipment, CNC machine tools, postal and telecommunications, copiers, refrigerators, microwave ovens, electric fans, washing machines, electronic game consoles, etc.
