What is a membrane overlay?
Elevate your product with a membrane overlay.
In your search for a membrane switch, you are likely to find that many switches come with a membrane overlay, a common feature in these electrical switches. A membrane overlay acts as a protective layer over the membrane switch that protects the circuitry from outside elements, such as moisture or other contaminants. They are typically ultra-thin and can be custom-designed as a layer to be applied over the surface of a switch. Membrane overlays perform several purposes – from the functional intention of switch protection, to enhancing the user interface, while also serving as an opportunity for branding and aesthetics.

An introduction to membrane overlays
As membrane switches are soft and flexible mechanical switches, they sometimes have a membrane overlay. These precision-engineered outer layers guard the switch from contaminants with a flexible material such as plastic or similar synthetic material that can withstand the harshest environments, such as extreme temperatures or chemical exposure. Choosing high-quality materials increases the lifespan of the membrane switch, while ensuring they will not fade or degrade over time.
There are different types of graphic overlays available depending on the device. Some require a panel overlay or touch screen overlay. However, membrane overlays are most typically used with membrane switches, applied with an adhesive for easy installation.
