Graphic Overlays or Membrane Keypads: What You Need to Know

By Sophie | 11th February 2025 |

Printed fascia panels are the heart of any control system, offering both functionality and visual appeal. As the first thing an operator notices, they set the tone for the user experience. But which option is better for your businesses needs: Graphic Overlays or Membrane Keypads?

What Are Graphic Overlays?

Graphic overlays combine style and durability, making them a standout choice for control panels. Key features include:

Custom Designs: Perfect for clear/tinted windows, dials, and knobs.
Advanced Finishes: Options like anti-microbial coatings, UV stability, and IP-rated durability (IP65-IP68).
Special Features: Phosphorescent graphics, hidden-till-lit designs, RFI EMC shielding, and even Braille.

Constructed with an under surface-printed layer and adhesive backing, graphic overlays are built to last, even in harsh environments. They’re cost-effective and versatile, with production techniques like Digital UV Printing and Screen Printing making them ideal for both small and large runs.

What Are Membrane Keypads?

If your project demands functionality beyond aesthetics, membrane keypads are the way to go. These control panel solutions integrate advanced features such as:

Integrated Circuitry: Offering tactile buttons and electronic functionality.
LED Displays: Enhance visibility with backlit or illuminated keys.
Custom Shapes: Precisely cut using techniques like digital flatbed and laser cutting.

Membrane keypads are not only functional but also deliver a sleek, user-friendly design, ideal for modern control systems. For added flexibility, rapid prototyping ensures your design works perfectly before large-scale production.
