Embossing Tactile Dome Membrane Front Panel Switch For Internet Touch Screen

Key Features

1. Embossed Design:

   • Provides tactile feedback, making it easier for users to identify buttons without looking.
   • Enhances usability, especially for applications requiring quick responses.

2. Membrane Switch:

   • Typically consists of multiple layers including a graphic overlay, adhesive backing, and a spacer layer.
   • The dome switches are positioned beneath the overlay and provide a click feel when pressed.

3. Applications:

   • Commonly used in consumer electronics, appliances, and industrial controls.
   • Ideal for touch screens where users might prefer physical feedback.

Design Considerations

• Material Selection: Choose durable materials that can withstand frequent use and environmental factors.
• Graphic Overlay: Ensure the design is visually appealing and clearly indicates each function.
• Circuit Design: Make sure the switch circuitry is reliable and compatible with the touch screen technology.

Manufacturing Process

1. Prototyping: Create a prototype to test the ergonomic and functional aspects.
2. Testing: Conduct usability testing to ensure the embossed features work as intended.
3. Production: Scale up manufacturing while maintaining quality control.

Lexans spec :

Material

• Common materials include vinyl, polyester, polyimide (Kapton), and polyethylene terephthalate (PET) films.
• The material needs to be durable, chemical/solvent resistant, and able to withstand temperature extremes.

Adhesive

• Pressure-sensitive adhesives like acrylic or rubber-based are common.
• The adhesive must have strong bonding strength to adhere securely to various surfaces.
• It should also resist peeling, lifting, and degradation over time.

Thickness

• Typical sticker thicknesses range from 2-10 mils (0.002" to 0.010").
• Thicker stickers are more durable but may impact conformability to uneven surfaces.

Size & Shape

• Industrial stickers come in a wide range of standard and custom sizes.
• Common shapes include rectangles, squares, circles, ovals, and die-cut custom shapes.
• Size is selected based on the specific application needs.

Here are some examples of common Lexan polycarbonate products used for industrial overlay and enclosure designs:

1. Lexan FMR (Flame Mitigating Resin) Sheets

• Formulated with flame-retardant additives to meet stringent fire safety standards
• Often used for control panel faceplates, switch plates, and equipment housings
• Available in clear, tinted, and opaque color options

2. Lexan EXL Impact-Modified Sheets

• Engineered for superior impact resistance and toughness
• Ideal for overlays, bezels, and enclosures that need to withstand abuse
• Maintains optical clarity and dimensional stability under impact

3. Lexan HPS (High Performance Sheet)

• Offers excellent chemical, temperature, and UV resistance
• Used for outdoor equipment, harsh environment enclosures
• Can be metallized or coated for specialized surface finishes

4. Lexan ML (Matte Low-Glare) Sheets

• Matte surface finish reduces glare and reflections
• Enhances readability of control panel graphics and displays
• Maintains clarity and scratch resistance of standard Lexan
