Product Description
Product Overview
Professional screen printing membrane switch pad featuring Pantone color matching, PET circuit construction, and tactile metal dome switches. These user interface components serve as the critical communication link between operators and equipment, instruments, or machinery.
Construction & Design
Membrane switches consist of thin layers bonded with pressure-sensitive adhesives, typically ranging from 4 to 9 layers depending on application requirements. The visible top layer is the graphic overlay with printed circuitry underneath, which can incorporate polyester (silver flex), polyimide (copper flex), and rigid PCB layers.
Key Advantages
- Cost-effective compared to mechanical switches
- Low-profile design saves space
- Easy to clean and maintain
- Sleek, ergonomic, and aesthetically pleasing appearance
- Switch activation occurs when printed shorting pad or metal dome contacts bottom circuit layer
