CE Customized Telecommunication Equipment Graphic Overlays
Product Description
The design of a Custom Graphic Overlay is often critical to creating a new electronic system or device since it forms the HMI (Human-Machine Interface) of the product that controls and indicates status.
Typical applications of Custom Graphic Overlays:
Membrane Keypads and Membrane Switches.
Protective Overlay: Over traditional mechanical switches.
Key Frame Labels: A button or switch comes through an opening in the Overlay.
Laminated panels: An overlay adheres to an engineered plastic or metal support panel.
Indicator Panel: Where LED and backlit displays indicate status separate from control.
Label Sets: Batched stickers and overlays supplied for hand application.
Graphic Panels: Display information, branding or point of sale.
(This is sometimes used in conjunction with touch products to add a permanent graphic layer over a capacitive touch switch.)
When designing a graphic overlay below three main questions need to be asked at the concept design stage:
What is the application?
• Commercial, Mobile, Medical etc.
Are there any environmental factors?
• Weather, Dirt, Lighting Conditions etc.
What surface is the overlay being applied to?
• ABS, Nylon, Powder Coated etc.
Many factors can shorten the life expectancy of a membrane keypad, and its protective Custom Graphic Overlay; light (UV), temperature, humidity and the physical surroundings all play their parts.
