Silicone Rubber Keypads – an alternative
interface for use in a variety of applications

For over a decade The Membrane Keyboard Company have been supplying Silicone Rubber Keypads. This technology offers engineers an alternative touch medium when developing a new HMI product. One of the main benefits of integrating a Silicone Rubber Keypad into a product is its versatility; allowing for exciting and innovative designs that are suitable for a huge range of applications in many markets.
Further design features include:

Mylar/Rubber Domes
Where a tactile response is critical, a mylar layer with snap domes integrated into it provides both positive tactile response and reduced key travel. As it can be bonded to a PCB, the part adds value to itself by reducing the likelihood of ingress from contaminant elements.

Laser Etching
The process of laser etching a painted rubber keypad involves the top layer of coating being removed from the key to reveal a lighter secondary layer below. The effect gained from this is the legends on the keys are enhanced by a back lit effect, making it perfect for use in light sensitive environments.

Plastic Key Tops
Where proof of a tactile response is required by the operator, this can be achieved by incorporating plastic key tops to the keys. By doing so this allows for both a functional solution to the problem and an aesthetically pleasing enhancement to the keypad as a whole.

Epoxy Cured Key Tops For keypads that may be exposed to rigorous or repeated use, the application of an epoxy or gloss layer to the top of each key can improve durability, whilst giving each key upon actuation a more noticeable positive feel and improved cosmetic appearance due to the curved surface that occurs after application.
