Waterproof Membrane Switch Design Guide

What Are Waterproof Membrane Switches?

Waterproof membrane switches are sealed user interface components designed to prevent water or liquid ingress. They typically consist of multiple layers including:

• Graphic overlay

• Spacer

• Circuit layer (PET or FPC)

• Adhesive sealing layer

Through advanced sealing techniques, these switches achieve different levels of waterproof protection.

IP Rating Explained (IP65 / IP67 / IP68)

Understanding IP ratings is crucial when selecting the right waterproof membrane switch:

• IP65 – Protection against water jets

• IP67 – Temporary immersion in water

• IP68 – Continuous immersion under specified conditions

At LuphiTouch, we design membrane switches according to your required protection level and application environment.
