Keypads & Switches

This category covers the direct connection for every Human-Machine Interface (HMI). We supply custom solutions: durable silicone-rubber keypads, flexible membranes, and precision metal-dome switches. We select specialised materials to withstand extreme heat, vibration, and chemicals. Our design ensures a reliable, satisfying tactile click.

We achieve high Ingress Protection (IP) ratings, sealing out dust and moisture completely. RH constantly innovate, integrating capacitive touch and hybrid solutions. We guide you through selecting the proper circuitry and backlighting. Trust our expertise to deliver interfaces that pass rigorous testing and last for millions of cycles.
