Materials

Base Material
The standard material used for membrane switches is Polyester. Other base material options include

• PET
• PEN

Conductors
Conductive inks are the most widely used conductors and can be applied in various thicknesses and line widths to meet each customer’s requirements. Additional conductor options include:

• Standard Silver Ink
• Highly Conductive Silver Ink
• Silver/Silver Chloride Ink
• Carbon Ink
• Copper
• Carbon/Silver blend

Insulators
Screen Printed Dielectrics are used to mask conductors from external elements and to provide insulating layers between multiple conductor layers.

Adhesives
Adhesives are used only when combining membrane switches with touchpads, keypads or some form of graphic overlay. Common adhesives include:

• Epoxy
• Acrylic
• Pressure sensitive adhesives
