Membrane Switches: The Smart Interface Solution Connecting Humans & Machines

What is a Membrane Switch?

A membrane switch is a sophisticated yet cost-effective interface technology that combines form and function through its innovative layered construction. These ultra-thin switches activate electronic functions through precise pressure-sensitive mechanisms, creating reliable human-machine interactions across countless applications.

Precision Engineering in Layers

Our membrane switches feature an optimized 5-layer architecture:

1. Graphic Overlay

   • Custom-printed polyester or polycarbonate surface

   • Unlimited color and design possibilities

   • Scratch-resistant and UV-stable finishes

2. Spacer Layer

   • Precision adhesive spacing

   • Maintains proper dome actuation

3. Dome System

   • Metal snap domes for tactile feedback

   • Polydome® silicone for silent operation

4. Circuit Layer

   • Silver or copper conductive inks

   • Flexible or rigid PCB options

5. Rear Adhesive

   • Secure mounting solutions

   • Removable or permanent bonding
