Custom Capacitive Touch Film Switch
Capacitive Touch Interface Layers Overview
FSR force sensors are versatile components used across a wide range of applications due to their ability to accurately detect pressure and touch.
Longer Product Life
Operates without physical contact, which enhances durability and extends product life.
Easy to Clean
The flat surface design eliminates hygiene dead corners, ensuring safety and cleanliness while reducing the risk of cross-contamination.
Transparent Design
Light transmittance exceeds 80%, maintaining visual clarity for backlit or display-integrated applications.
Waterproof and Dustproof
The seamless integration of circuit and panel prevents ingress. Waterproofing can reach IPX7 level, offering strong protection against environmental factors.
Easy to Install
The functional material layer is less than 0.3 mm thick. It can be bonded to panels using double-sided adhesive, allowing it to conform to curved or irregular surfaces. Lightweight and easy to install.
Multi-Touch Capability
Supports single-point touch via self-capacitance or multi-point matrix touch via mutual capacitance. Can also be configured for slider-type multi-touch input.
ESD Protection
Electrostatic discharge is mitigated through the design of conductive grid circuits around the circuit layer, grounded for effective ESD shielding.
