The Backlit Keypad, also known as a backlit keyboard, elevates the functionality and visual appeal of keypads through the integration of LEDs. Typically made from materials such as silicone rubber, plastic, and metal, these keypads are often referred to as silicone rubber backlit keypads. By utilizing translucent or transparent silicone materials, these keypads optimize backlighting for superior performance. Various techniques, including laser engraving, screen printing, spray coating, and PU coating, are employed to achieve exceptional backlighting effects.
Types of Silicone Rubber Backlit Keypads
Laser Engraved Backlit Keypad
Laser engraved backlit keypads involve a meticulous process where the basic silicone keypads are first spray coated with color. Subsequently, laser engraving is used to create the desired backlighting effects. To protect the spray-coated layer and legends, many of these keypads receive a protective PU coating or a matte smooth finish post laser engraving.
Translucent Silicone Backlit Keypad
These keypads capitalize on the natural translucency or transparency of silicone. The degree of transparency varies depending on the quality of the silicone material. Some keypads utilize a protective cover tool to maintain the translucent parts and undergo a two-layer spray coating process, while others opt for a mixed color method for reduced transparency. It is important to note that the former technique, although more effective, tends to be more expensive.
Silk Screen Printed Backlit Keypad
Silk screen printed backlit keypads stand out by omitting the spray painting step typically required before font or symbol printing. This approach streamlines the production process. For enhanced backlighting effects on legends, some of these keypads forego the PU coating or choose UV+PU coating, relying instead on the inherent transparency of the silicone material.
Customizable Options
Backlit keypads are available in various customizable options to suit different applications and preferences. Wholesale suppliers offer a range of configurations, allowing for tailored solutions that meet specific design and functionality requirements.
Applications and Benefits
Backlit keypads are widely used in numerous applications, including consumer electronics, automotive controls, and industrial equipment. The integration of backlighting not only enhances the aesthetic appeal but also improves usability in low-light conditions, providing a better user experience.
