INNOVATIVE DESIGNS
Dyna-Graphics Corporation, A World Leader in Membrane Switches, with innovations like “K-Motion©” Technology brings you solutions to your most demanding challenges in Membrane Switch Design and manufacturing. From Environmentally Sealed Membrane Switches to Tactile-feel Membrane Switches, we can custom design and produce a Membrane Switch to fit your needs.

The illustrations below represent the “Sandwich” Construction of a typical Membrane Switch. Contacts and circuitry paths are screened with conductive silver ink on polyester film (circuit layers). These films are separated by an insulating sheet (spacer) with holes that separate the contact points from each other or may contain the domes for a tactile application. The circuit is “Closed” and “Opened” when pressure is applied and released.

	Designed with contact circuitry and using metal domes, these types of membrane switches provide excellent tactile-feel and response. Using different size metal domes---from 8mm, 10mm, 12mm, and rectangular domes--a number of actuation pressures and sensitivities can be achieved. These are ideal choices when a “physical” response is required.
Non-tactile designs feature micro-travel with actuation forces typically in the 4-8 ounce area, depending on the thickness of the spacer used. Embedded L.E.D.’s can be adhered to the conductive silver traces for lighted windows and display areas. Non-tactile and metal dome tactile membrane switches have been tested to well over 5 million cycles to ensure high reliability.
	Tactile-feel is achieved using a thermoforming process to “dome emboss” the upper conductive pads. Typically an upper and lower spacer are used to achieve the tactile feel. All designs offer a cost effective solution for any adaptation you create.

K-Motion Membrane Switches

• The conductive silver pad areas are separated by a screened dielectric spacer, usually dielectric dots. They are ideal in a situation where low actuation forces is needed.
• Actuation testing: 5,000,000 cycles with 10 mil. Velvet Lexan with no damage to switch or fascia.
• Dielectric withstanding voltage: 500 VDC for 120 seconds
• Heat-stabilized 5 mil. polyester with 3M 200MP adhesives. Silver-filled conductors U.V. cured dielectric.
• A very cost-effective membrane switch

EMBEDDED L.E.D.’s

• Surface-mount L.E.D.’s are adhered to screened conductive silver traces using a flexible silver-filled epoxy adhesive. The low-profile of the L.E.D.’s (.043” x.126”) makes them an excellent choice for backlighting applications and front panel illumination.

GRAPHIC OVERLAYS
STATE OF THE ART GRAPHIC DESIGN
Advanced Subsurfaces Printing Techniques are used to screen legends and background colors (on the reverse side) of the graphic layer. This ensures the long-lasting durability of the keyboard and, at the same time, creates an impressive and accurate reproduction of color and graphics.

Flexibility of Design
Your Panel Overlay visual requirements are limited only by your imagination and creativity. Dyna-Graphics Corporation uses advanced technologies in the application of colors, legends - any size or shape - almost any aesthetic design or format can be accomplished. U.V. Selective Texture and UV Hardcoat can be screened to protect lens areas from chemicals and scratching. Add Embossing to your Panel Overlay and it becomes a product with 3 Dimensional characteristics..

Lighted Displays
Dyna-Graphics can effectively and appropriately utilize Hard Coated Lenses for the enhancement of Incandescence, L.E.D., Fluorescent Gas, and Liquid Crystal Displays in your Panel Overlay. The light source may be exposed or totally sealed. It any be viewed at all time or "dead front" (seen only when on or activated). The dead front may also be adjusted to accommodate the strength of the light source; different light sources may be used in the same switch panel, such as Fluorescent Gas Displays and a Digital LED, as well as individual L.E.D.'s.

Materials
Depending on the application, Dyna-Graphics uses Polyester Films or Polycarbonate Films. Because Polyester Films offer greater chemical resistance and flex life, they are the most common. Both materials are available with textured surfaces. In most instances, Dyna-Graphics Corporation uses 3M Brand Adhesives for bonding of the different layers.

PCB ASSEMBLIES

Dyna-Graphics Corporation's high technology PCB Membrane Switches are designed with fewer pieces of hardware. Being that there are fewer pieces of hardware and no metal panel, there is less assembly time and fewer inventory items. PCB Assembles and LED's can be assembled closer to the back of the Lens and give better visual clarity to the end user. Miscellaneous components of almost any nature can be place in a PCB Assembly as long as space permits. This is especially convenient with LCD Displays where certain components need to be physically close to the display. This type of arrangement provides extra space when other circuit boards are full. Dyna-Graphics Corporation has merged its advanced and Superior Membrane Technology Design with Circuit Board Technology to create a new reliable line of products. This new innovation in design involves a PCB as the main structural substrate with the Membrane Switch on the front and the display, plus other components on the back side. This advanced technology in construction has several distinct advantages for you, because better design technologies lead to overall cost containment.

RUGGED LINE
MEMBRANE SWITCH PRODUCTS
The Rugged Line Membrane Switches are designed to maintain their integrity under the most demanding circumstances . This switch configuration can be used in applications where the switch will see some abuse from sharp objects such as pens and screwdrivers, and keep right on working. The switches utilize some of our current technology and add some new ideas as well. It's part of Quality and Innovation you've come to expect from Dyna-Graphics!

The circuit portion of the assembly is our non-tactile K-Motion Membrane Switch. The trip force is light enough to be actuated through the protective overlay material. The reliability of our K-Motion Technology has been proven throughout the industry in thousands of applications over many years.

The overlays for Rugged Line Membrane Switches are made with .030 Polycarbonate. With an overlay that thick,there is excellent protection for the switch circuitry and your display.

In applications where the end users abuse your equipment, the Rugged Line Overlay offers maximum protection. The typical Membrane Switch has 6 to 10 mils, of Overlay on the front surface, whereas the Rugged Line Overlay offers 30 mils., and possibly thicker in some applications. Delicate LCD's can be hidden behind a 30 mil. lens without a lens insert or a cutout in the Overlay. All printing is done on the back of the Overlay and we can seal the Switch from moisture with our gasketing techniques and our Water Seal Adhesive (WSA). All of the improvements we've developed over the years are incorporated into one with our Rugged Line Membrane Switches!

TYPICAL K-MOTION SWITCH SPECIFICATIONS

• The conductive silver pad areas are separated by a screened dielectric spacer, usually dielectric dots. They are ideal in a situation where low actuation force is needed or for a Rugged Line Membrane Switch where the Overlay is thicker than most conventional Membrane Switches. The K-Motion Switch is sensitive enough to be actuated through a 30 mil. Overlay reliably without actuating adjacent switch locations.
• The circuit layers are heat stabilized Polyester Polyester with 3M 200MP series adhesives.
• The conductive traces are silver.
• Actuation testing has revealed 5,000,000 cycles with no damage to the switch or overlay.
