Pennsylvania Membrane Switch Manufacturers Suppliers

When the user presses the keycap the full key travel distance, a contact point at the top of the dome pushes the top layer through a hole in the middle layer to contact the bottom layer. This closes the circuit which actuates the keystroke, and the keyboard will then send the character information to the computer. The middle layer of the membrane keeps the top and bottom layers from contacting each other except when a switch is depressed completely. Differences in the shape and thickness of the domes determine the travel, resistance, and tactile feedback of the switch, however the keystrokes are only generated when the key is fully depressed.

All these guarantee membrane switch, touch switch, and seat occupancy sensor to be quality-reliable and price-favorable. We embrace challenges and transform tangibles into value experienced by the customers. Membrane switches are available in various forms and are capable of providing different feedback levels to the user. When you work with us, you’ll notice we use terms such as audible, tactile, snap acting dome and poly-dome when discussing the feel and behavior of your membrane switch. The top layer of these switches uses a graphic overlay and consists of a printed circuit underneath. The switch panels can be directly connected to the electronic equipment by a flexible tail termination and consist of several layers of polyester and adhesive.

The most common types of domes are made of stainless steel or polyester. These two technologies are quite similar and offered no significant difference in their capabilities. Ideal for for low volume production or for the prototype of a new membrane switch program, our line of stock membrane switches are available through a distribution network with no tooling or engineering design cost. Xymox stock membrane switches are normally open, momentary contact, push button type devices. Layers of insulating materials, conductive coatings and adhesives are combined to form a completely sealed switch, ideally suited for switching low energy logic signals. We have been a leader in the design and manufacturing of membrane switches since the technology was born in the late 1970’s. So, when our customers demand excellence for their application – whether it’s a custom build or a stock membrane switch design – they know Xymox will deliver every time. For these kinds of custom membrane switches, we usually utilize PCBs or copper flex to create the circuit layer. Among other things, this gives us endless options for creating whatever kinds of electronic components our clients demand. A membrane switch is an interface between user and machine, enabling an operator to communicate with equipment, instrumentation, or machinery.

For example, the key may be capable of traveling 4 mm before hitting the bottom of the keywell, but the keystroke is generated after 2 mm. This means that when typing, there is no requirement to travel the full key travel distance. This affords touch typists the luxury of not pressing keys fully down, reducing the constant jarring action on fingertips when ‘bottoming out’ and associated unnecessary muscle action. Most non-linear mechanical keyswitches offer increasing resistance after the keystroke is generated, encouraging the user to stop pressing down the keycap and instead move on to the next keystroke. Finally, keycaps snap back to the starting position (i.e. up) more quickly than other keyswitch types, facilitating faster typing speeds. Circuits can be printed using silver conductive ink, etched copper flex or printed circuit boards (PCBa’s). Our customers put our 30+ years of membrane switch experience to work for them.

Using waterproof membrane switches is the best way to protect your investments, saving you money, time, and stress. If you have any questions about user interfaces, Ken Boss will be the one to answer them. He’s been working for us for over 30 years and knows more about membrane switches, graphic overlays, and UL labels than anyone we know. We work with custom color LEDs, fiber-optic panels, diffusion materials, and opacity solutions including black gasketing materials to provide precise control of lighting panels.

Depending on the application requirements, a membrane switch will consist of as few as 4, and as many as 9 layers. Electrical switches that turn circuits on and off, membrane switches enable communication capabilities for many different types of technology products, equipment and systems. These interface utilities can be simple tactile switches that control lighting, touch-screen panels, plastic keyboards or toggle switches. Vexos also provides Electronic Manufacturing Services and complete end-to-end Supply Chain Management solutions for electronic and mechanical products for Original Equipment Manufacturers . Complex user interface designs often need more components than their simple switch counterparts, usually resulting in more layers. Multi-layered switches may include some form of ESD, EMI, or RFD shielding, embedded components like LED’s, resistors, light sensors and even programmable chips. To accommodate these more robust designs we are often using copper flex or PCB’s for the circuit layer. The adhesive is important in two layers of membrane switches; it combines the switch to the graphic overlay and will bind the entire assembly to your product. There are numerous differences in adhesives; selecting the proper adhesive for application requires consideration of environmental, surface, appearance and other performance requirements.

A membrane switch is a user interface that utilizes circuitry printed on layers of flexible polymer film. When actuated, the membrane switch circuitry is momentarily closed and provides an electrical signal to the main circuit board. Membrane switches typically have several layers that incorporate a graphical interface with an electrical circuit. Membrane switches are a reliable and cost effective user interface that can be fully customized to meet your specific needs. Since 1973 Consolidated Products Company has been a leader in the printing industry.

But it also comes with some disadvantages you should be aware of. Polycarbonate begins to show signs of wear sooner than alternative materials. In most applications, overlays made of polycarbonate will last 100,000 cycles during lifecycle testing. Note that uncoated polycarbonate might be susceptible to damage from chemicals. If your polycarbonate overlay is going to be used in a harsh environment where it might be subjected to chemicals, you should definitely cover it with a hard coat for protection. Manufacturers can design digital windows to boost the specific display used in your application. The texture might distort the appearance of a display that is not directly against an overlay. Moreover, you can take advantage of translucent filtering inks that can be printed to enhance the display’s appearance.

That’s why we recommend to add a hard coat to gloss materials to ensure its long operation. Faceplate Requirements – all of the details required for the top layer that carries all of the colors and defines the key nomenclature. Compatible with custom faceplates – Custom appearance is achieved by mounting one or more switches behind the custom faceplate of your design. Clear Encapsulant – UVD-11 Clear Encapsulate was developed to provide additional mechanical strength in attaching a component to a substrate. It is a UV cured dispensable coating compatible with thermally cured epoxies and is suitable for both flexible and rigid substrates. Crisp Tactile Feel – due to the process and the dome geometries developed, Xymox ensures a firm “snap” throughout the specified life of the switch.

Circuitry is designed using either a common bus or a matrix configuration, or a combination of the two. The connection from the membrane switch to the PCB can be made one of three ways. On an area where high transparency is required, like LCD window, the shielding can not be made by above solutions, and then the ITO film or PET printed with transparent conductive polymer shall be applied. PCBThe Printed Circuit Board is used to support and connect electronic components using conductive pathways, or traces, etched from copper foils laminated onto a substrate. A patented structure called PushGate contains magnetic island and metal armature to provide anti-violance protection on the botton. A normally closed circuit can be made by using the PushGate button; it also supports circuit of both normally closed and normally open to be built in same keypad. Gradient printing can be done by inkjet printer, offset printing, or silk screen printing. Firstly, check the environment in which the membrane switch is to be used. If the environment is dusty, the surface to be laminated needs to be cleaned and the surface to be laminated needs to be flat, rust-free and oil-free.
