The MI Shielded Membrane Switch is a high-reliability human-machine interface (HMI) switch that combines a membrane switch structure with a metal shielding layer. It features multilayer flexible circuits with integrated metal shielding to effectively suppress electromagnetic interference (EMI), electrostatic discharge (ESD), and signal noise. Ideal for medical devices, industrial controls, military instruments, communication equipment, and testing instruments requiring high EMI/ESD immunity.
The switch offers high durability, precise tactile feedback, and customizable backlighting options (EL, LED, or light guide), along with configurable graphics, legends, and functional layouts.
The MI Shielded Membrane Switch combines traditional membrane switch technology with an internal metal insert or shielding layer. This effectively protects the circuit from electromagnetic interference (EMI) and electrostatic discharge (ESD), ensuring stable signals and reliable key response.
EMI & ESD Protection: Built-in metal shielding reduces environmental noise and enhances system stability.
High Durability & Tactile Feedback: Long-life membrane construction and high-reliability contacts provide consistent key response.
Multilayer Flexible Circuit: Supports 2–6 layers or more for complex layouts and functional requirements.
Customizable Backlighting: EL, LED, or light guide backlighting options to fit design needs.
Engineering-grade Materials & Process: Designed for high-temperature and high-humidity conditions, suitable for industrial and medical environments.
Medical Devices: Ultrasound machines, monitors, diagnostic instruments requiring reliable input and EMI protection.
Industrial Automation: PLC control panels, field operation interfaces, robotic control panels.
Testing & Measurement Instruments: Oscilloscopes, power supply testers, and precision test equipment.
Military & Communication Terminals: High-precision switches in EMI-sensitive environments.
