Polycarbonate Chrome Ink Printing Mechanical Key Switches For Medical Equipment

Types of Mechanical Switches

1. Tactile Switches: Provide a noticeable bump when actuated, offering feedback without being excessively loud (e.g., Cherry MX Brown).
2. Clicky Switches: Feature an audible click sound upon actuation, providing both tactile and auditory feedback (e.g., Cherry MX Blue).
3. Linear Switches: Smooth and consistent keypress without any tactile feedback or noise (e.g., Cherry MX Red).

Key Characteristics

• Actuation Force: The amount of force required to press a key. Different switches require different amounts of pressure.
• Travel Distance: The distance a key travels before it registers a keystroke. Typically ranges from 3.5mm to 4mm.
• Durability: Mechanical switches are generally rated for tens of millions of keystrokes, making them long-lasting.

Advantages

• Customizability: Many mechanical keyboards allow users to replace switches (hot-swappable) or customize keycaps.
• Typing Experience: Users often report a more satisfying typing experience compared to membrane switches.
• Gaming Performance: Mechanical switches can provide faster response times and better accuracy for gaming.

Popular Brands

• Cherry: One of the most well-known brands, offering a variety of switch types.
• Gateron: Known for smooth keystrokes and often considered a budget alternative to Cherry.
• Kailh: Offers a wide range of switches, including specialized options for gaming.

Polycarbonate

• Polycarbonate is a type of thermoplastic polymer known for its high impact resistance and optical clarity.
• It is a popular material choice for industrial control panels, equipment covers, and overlay graphics.
• Key benefits of polycarbonate include:
  • Durability - High impact and scratch resistance
  • Transparency - Can be clear or tinted/colored
  • Machinability - Can be easily fabricated and molded
  • Thermal resistance - Withstands heat and cold well

Panel 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.

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. The typical thickness range for polycarbonate front panes used in industrial control panels can vary, but generally falls within the following ranges:

   Standard Thickness:
   1.5 mm to 3.0 mm
   This is the most common thickness range for basic polycarbonate front panes. This thickness provides a good balance of durability, optical clarity, and cost-effectiveness.

   Thicker Panels:
   4.0 mm to 6.0 mm
   Thicker polycarbonate panels may be used in applications that require enhanced physical protection or larger panel sizes. The increased thickness adds more impact resistance and rigidity to the front pane.

   Specialized Thicknesses:
   0.75 mm to 1.25 mm
   8.0 mm to 12.0 mm
