Product Description
PET Membrane Switch Keypad with Tactile Dome & Blue LED
Product Overview
Custom membrane switch keypads combining flexible printed circuits with tactile dome feedback and integrated blue LED illumination for enhanced user interface experience.
Construction & Components
Membrane switches consist of two flexible printed circuits separated by a spacer. When pressed, the circuits contact through spacer holes to complete the circuit. The graphic overlay, typically made of clear polycarbonate or polyester, is reverse-printed for durability against wear, solvents, and abrasion.
Key Features & Capabilities
- Thin, durable momentary switching technology
- Tactile dome feedback (170-397g operating force)
- Integrated blue LED illumination
- Multiple layer construction with soft insulating materials
- Optional LCD transparent windows and EL backlighting
- Custom design solutions available
