China Waterproof Custom Membrane Switch Supplier With Gold-Plated
Metal Dome
What are the waterproof membrane switch ?
Waterproof membrane switches are a type of keypad or button
interface that use a flexible, sealed membrane to protect the
internal electronic components from water, moisture, and other
environmental contaminants. The membrane acts as a barrier to
prevent liquid ingress.
How do they work?
Waterproof membrane switches use a layered construction, typically
consisting of:
1 Top surface - A durable, water-resistant material like polyester
or silicone.
2 Spacer layer - Provides separation between top and bottom layers.
3 Conductive contacts - Printed circuit patterns that register
button presses.
4 Bottom substrate - Rigid or flexible material that supports the
circuitry.
When the top surface is pressed, it contacts the conductive layer
below, registering the button activation.
Key Features:
Water/moisture resistance - Can withstand splashing, submersion, or
high humidity environments.
Rugged construction - Designed to be durable and withstand harsh
conditions.
Tactile feedback - Can provide a positive "click" sensation when
pressed.
Customizable design - Can be tailored to specific shapes, sizes,
and button layouts.

Waterproof membrane switches are commonly used in:
Industrial equipment
Medical devices
Outdoor/marine electronics
Consumer appliances
Automotive controls
