Polyester(PET) Flat Membrane Switch, Metal Dome Membrane Switch Customized Design
Membrane Switch Components
Membrane switches typically have the following basic layers:
Graphic overlay with subsurface printed text/graphics and a polyester or polycarbonate layer with or without embossed keys
ESD shielding layer (optional)
Spacer and/or dome retainer
Polyester printed circuit layer
Rear adhesive with liner
Membrane Switch Materials
The graphic overlay surface or faceplate material is one of the main considerations in designing a custom membrane switch, with polycarbonate and polyester being the most commonly used materials. Polycarbonate is clearer, easier to fabricate and print but is less durable in constant use. Polyester is more challenging in its manufacturing, yet it is more durable and has better resistance to environmental conditions. Polycarbonate is slightly less expensive than polyester, but the difference is minimal and not usually a major consideration.
Our membrane switch design and engineering team will guide you to help you chose the best membrane switch product based on your needs and the conditions in which the membrane switch will be used. Hard-coated materials are also available to reduce gloss/glare and provide added durability, scratch-resistance, and chemical resistance.
