Our membrane switches offer user-friendly operability for a better end-user experience. Or please contact us here to start developing your custom membrane switch today. After screen printing the conductive inks and silver paste, we adopt hot air circulating tunnel furnace for baking. Furthermore, the baking temperature is 110 degrees, and the speed is 5 meters per minute. While, a UV curing oven is used for baking the screen printed UV layer, and the parameter is 500 joules. A good performance polyester film is used as a carrier for the switching circuit pattern. Screen printing the conductive silver paste, conductive carbon paste and UV layer. What’s more, the UV layer is used to protect the circuit effectively. Here’s an example of a 3×4 matrix keypad wired to the Raspberry Pi. To meet the diversified needs of our valued clients, we are engaged in offering PCB Membrane Keypad.
It is important to select proper overlay material depending upon the application. We use special grade polyester which is very suitable for embossing and gives good chemical and scratch resistance. In order to make a impressive and attractive overlay, it is important to choose proper color, shade, font size, font shape etc. LUPHITOUCH has our PCBA factory, can provide the PCB assembly, FPC assembly, PET circuit assembly service. Have the capability and permission to design and manufacturer medical market used keypads, integrated assemblies.

If your company requires a custom-designed membrane switch, whether as a standalone product or part of a larger concept, BTI has a solution for you. If you would like to learn more about our collaborative design process, rigorous quality standards, and competitive pricing, give us a call today. A membrane keypad with raised embossed keys highlight the entire key area. The keys are constructed with an underlying metal polydome or spring dome that gives the user feedback when activated. The choice of dome depends on the area of use, tactility and the surrounding temperature. In fact, advanced technologies in Hoffmann + Krippner membrane switches open completely new avenues for product design in these areas, including antimicrobial surface preparation . Additionally, due to its high voltage and frequency, EL lighting is often not permitted in medical technology, while H + K’s LED-based keypad lighting can be used freely. Assembly the metal dome with the bonded graphic adhesive, upper circuit layer, and adhesive separator. It can’t be installed on the reverse, missing and multi domes loading.
Consumer electronics integrate them into switching control panels and remote controllers for comfort, portability, and economy of space. Moisture seals can be added for the extra durability your device needs. This protective layer is submersible and able to withstand moisture and water spray. We at Butler Technologies Inc. hold ourselves to high-quality standards to ensure that every layer excels in function and durability. Ideas for designing award-winning control panels that create satisfied users, work reliably in all environments throughout the product life, and differentiate you from the competition. To highlight the visual 3D effect, the panel is designed with colour and lacquer on the embossing. On the other hand, the link you’ve posted includes the controller board as well, so that might be responsible for the higher pricing. This is a rough outline of what you’ll need to do to replace a keypad from a microwave, washing machine ,etc. Creative aesthetics and exclusive design possibilities, e.g. application of the domes onto company logos, displays, LEDs, etc. Check if there are any problems such as scratches, crushing, dirt, offset, unclear printed lines, and severe deviations.
Wireless phones and devices may be returned within 14 days of purchase. When returning a wireless phone or device with a plan, you are responsible for ensuring that your service is cancelled with the carrier. If you don’t cancel your service, you may incur additional charges from your carrier. Ultra-thin design & adhesive backing provides easy integration to any project. This allows a microcontroller to ‘scan’ the 5 output pins to see which of the 4 buttons is being pressed. Trying out different keyboards before you finalize your choice should be a practical solution.
A closed-loop is created when it connects with the upper circuit layer or the dome switch due to pressure from the outside. This closed-loop causes the actuation of the desired switching effect. Made of polyester or polycarbonate, it can be screen printed or digitally printed to your specifications to tell users how and where to press. The overlay typically will have letters, symbols, and icons printed on to indicate where to press. Embossed domes may be designed under the icons for a more intuitive button interface. We produce quality membrane switches and keypads for a variety of industries including home healthcare, gas-detection equipment, and industrial controls.
Spacers and adhesive layer – adhesives which are double-sided self-adhesive polyester films covered with a layer of acrylic adhesive. They are used for gluing different films and circuit layer together, also for the keypad to the enclosure or supporting plate mounting. The keypad pins are referenced left to right if the keypad is oriented upright and facing you, i.e. pin 1 is the first pin on the side of the header closest to the 1-column on the keypad. Being a well established enterprise of this industry, we are engaged in offering a vast range of Capacitive Keyboard. This keypad is designed and manufactured using best quality basic material and highly developed techniques. Owing to perfection and quality oriented approach, we are involved in offering a high quality Tactile Membrane Keypad. We assure our valued patrons that the offered keypad is the best on counts of quality as well as functionality. This keypad is manufactured using quality assured basic material and cutting-edge technology by our dexterous engineers at our well-established manufacturing unit.
There is less tactile sensation from membrane keyboards than there is when individual key switches are used . When different electronic products came into existence more than 30 years ago, the membrane keypads were used as the operating panels. These push button keypads had problems because of undesirable tactile response. As technology developed through the years, the modern membrane switch have evolved to avoid these problems by customizing how these switches are built to fit the product and how it is used. Most often, they are now composed of 4 or more layers of substrate joined together like a “sandwich” and attached by a pressure-sensitive adhesive so that all you see outside is the graphic interface. We often think we’ve made every sort of membrane keypad imaginable but then a client comes along with a new set of requirements. From simple small non-tactile membrane switch panels to large, feature rich, membrane keyboards in complex assemblies, we can provide the solution required. The key factor in achieving a successful design is an early dialogue. The membrane keypad should be considered at the same time as the electronics and enclosure of a product, not late in the design process after these other elements are firmly established.
