Product Description
Flex & Rigid Membrane Switches
Details of Flex & Rigid Membrane Switches
The circuit of membrane switches can be flex and rigid. It depends on the customer end application and also related to the cost budget and other considerations. For example, life, resistance, connection type on main board etc.
For the flex circuit membrane switches, there are two types. They are silver printed PET circuit and copper etched FPC circuit. Their difference and advantages&disadvantages listed bellow:
Items | Silver Printed Circuit | Copper Etched FPC Circuit |
Material | PET (Polyester) | Copper |
Conductor | Printed silver | Copper |
Contact Fingers | Silver and Carbon | Gold plated |
Contact Buttons Pads | Silver | Gold plated |
Life & Reliability | normal | good |
Stability | normal | good |
Resistance | low | Very low |
Cost | low | high |
Lead Time | 2-3 days | 7-10 days |
Pitch | 0.5mm (not suggested), 1.0mm,1.27mm,2.54mm | 0.5mm, 1.0mm,1.27mm,2.54mm |
Usually if the membrane switches need assembled many LEDs, then we suggest to use FPC circuit, it can get more stable LED soldering quality. For the normal application the PET circuit is enough, which is more economical. In addition if the conductor pitch is 0.5mm, although we also can print it, but we still suggest to use FPC circuit. Because of that 0.5mm pitch is too small and it is easy to occur the short circuit problem.
For the Rigid circuit membrane switches, the circuit is rigid printed circuit board. The material of rigid PCB is usually FR4 and Copper. By this type of membrane switch, the connector usually is the SMD connector(sometimes also can be straight through connector). For some application which need very stiff capability, then use PCB circuit membrane switch.
Dongguan LuPhi Electronics Technology Co., Ltd. is a professional manufacturer of high quality HMI products and electronics project assembly, offers a wide range of innovative membrane switch panel capabilities. LUPHI utilizes the latest switch panel technologies, high quality imported raw materials and specializes in integrated switch panel assemblies. These membrane switch panels are ideal for a variety of medical industry application. LUPHI's membrane switch panels can be ergonomically designed for ease of use.
LUPHI's dynamic membrane switch panels feature embossed graphics, integrated LED's, selective solvent resistant textures, colored window displays, waterproof, LGF backlighting, custom sheet metal backers or enclosures and ESD shielding. These panels can be designed for specific environments including operating rooms, diagnostic centers and bedside use where sealing and durability are required.
LUPHI's highly knowledgeable Field Applications Engineers hasve extensive medical device experience which aid the design process. Additionally, LUPHI can integrate switches from its broad catalog offerings such as E-stops, key switches, toggles and pushbuttons with necessary wiring harnesses included.
Panels are typically designed with Ni-plated metal dome for a durable tactile response but can also incorporate polyester domes or be supplied without tactile feedback. Mechanical switches can be integrated in the design to provide additional functionality. For most applications, a NEMA-4 or IP65 seal can be achieved and, for more demanding applications, IP67 can be achieved. For flexible panels, a variety of interconnect technologies can be utilized to provide the best connection to suit the customer's packaging.
About LUPHI Since 1998, LUPHI has started the business of the HMI products in China mainland. Offering one of the broadest product lines on the market, LUPHI's products line includes super big size membrane switches, big size PET printed circuits, LED backlighting membrane switches, LGF backlighting membrane keypads, El backlighting keypads, capacitive membrane keypads, PCB/FPC circuit membrane switches, rubber keypad, LCDs, touch panels, OCA full lamination processing, PCB Assembly, turnkey project assembly etc. For more information about LUPHI or its broad line of products, contact us right now for your needs.

Dongguan LuPhi Electronics Technology Co., Ltd. (short for LUPHI bellow) is established in 2008. It located in Ziliang High-Tech Industrial Park, Huaide, Humen of Dongguan. The factory area is about 3500 square meters. It close neighbors to Shenzhen, Guangzhou and Hongkong. To Shenzhen airport is just about 30 minutes and to Guangzhou Baiyun Airport is just about 1 hour. LUPHI is a newly high-tech enterprise for human interface technology and metal, plastic molding, electronics product development, design and assembly.
Our main business and products include designing and manufacturing various kinds of super big size membrane switches, membrane keypads, graphic overlays, membrane circuits, various kinds of backlit membrane keypads like the LED backlit membrane switches, EL backlit membrane switches, LGF backlit membrane switches, the high-tech capacitive membrane switches and nameplates, labels, PCBA, prototype to middle volume metal + plastic + electronics turnkey project assembly.
At the beginning of establishing of LUPHI, we made the factory planning as per the requirements of our customers from USA and Europe, and the international standard. We invested big money to get many new and high accuracy big size semi-auto silk screen printing machines, high-performance pneumatic punching machines, hot embossing machine, high accuracy laser cutting machine, auto die cutting machine etc. LUPHI always regards the quality as our life. We established our inner testing room. We have many high-grade testing machines and equipments in our testing room, like the life testing instruments, 2D measurement instrument, high-low temperature environment test equipment, friction tester, dropping tester, electrical function testing instruments, ink adhesion tester etc. In addition, we also have the high clean room and anti-static clean booth to ensure the product reliability and stability for those high-accuracy and anti-static required products. By such kind of advanced hardware facilities and our experienced quality management team to ensure that each batch delivery to meet our customers' high quality requirements.
We organize the various kinds of training to our employees regularly. For example the product knowledge training, operation and assembly training, quality sense training, fire prevention training etc. To ensure our workers have the skillful operation technique to meet our promise of the on time delivery to our customers from all of the world.
80% customers of LUPHI are from USA, Australia, UK, Germany, Austria, France, Italy, Belgium, Sweden, Russia, Ukraine etc. Countries and areas. We know the overseas customers' requirements and business procedures very well. On this basis, we established our own perfect business development, engineering development & design, artwork making, production and quality control system.
We promise to use high quality raw materials to ensure our products achieve the quality goal of our customers. For example, we use Autotype PET, Lexan PC from GE, Korea Changsung silver paste, ACHESON silver paste, Japan JUJO inks, Nicomatic, CJT connectors, 3M adhesive, Luxking spacers etc.
