Custom Resistive Membrane Switch

A membrane switch is an electronic input device manufactured by laminating flexible film materials, integrating key graphics, circuitry, and switching functions into one unit. Characterized by its thinness, sealing property, aesthetic design, customizability, and cost-effectiveness, it is widely applied in electronic products and equipment requiring user input interfaces with high demands for sealing, space efficiency, and appearance. It serves as an important form of modern human-machine interaction interfaces.

Key Features

Tactile Feedback Options

We offer multiple tactile feedback configurations to suit different user experiences including metal dome, material embossed and flay type. Learn more about our tactile membrane switch.

Backlighting Solutions

We provide flexible backlighting options for visibility and aesthetic enhancement including LED, Light Guide Film (LGF) and Phosphorescent Ink. Learn more about our backlighting membrane switch.

Sealing & Waterproofing

Our membrane switches offer strong environmental sealing:
Standard Waterproof Rating: IPX4 to IPX6.
Enhanced Protection: Achieve up to IPX7 by using high-grade waterproof adhesives and added sealing layers.

UV Resistance & Antimicrobial Options

UV Resistance: Uses UV-resistant overlays and inks, ideal for outdoor applications.
Antimicrobial Coating: Optional top layer coating resists bacterial growth and supports UV sterilization, making it suitable for medical environments.

EMI Shielding

To prevent electromagnetic interference:
We apply conductive grid designs in the circuit layout.
Additional metal foil grounding on both front and back layers can be added for comprehensive EMI shielding.

ESD Protection

Our switches use anti-static materials with a surface resistance of 10⁸ ohms. Conductive grid patterns around the circuit perimeter are connected to ground, ensuring effective Electrostatic Discharge (ESD) protection.
