3M Membrane Switch Spacer Single Coated 7997MP features 3M High Performance Acrylic Adhesive 200MP, formulated for excellent shear strength, on a 5 mil carrier. This white PET film provides a smooth, bright appearance, eliminating the need for floodcoat on overlays and keypads. The adhesive withstands repeated switch actuation and forms neat, clean edges for precise slitting and die-cutting.

  • Excellent for graphic overlays and keypads
  • 7 mil single-coated spacer is ideal for withstanding repeated stress of switch actuation
  • 2 mil 3M™ Acrylic Adhesive 200MP delivers excellent shear strength, resists slippage and edge lifting
  • Clear 5 mil polyester film carrier adds brightness, eliminating need for floodcoat
  • Heavy 94# polycoated kraft (PCK) liner delivers improved handling and lay-flat
  • Adhesive resists oozing at slits and die-cuts for faster part processing

Resilient and Ready

3M™ Membrane Switch Spacer Single Coated 7997MP is constructed with 2 mil high performance acrylic adhesive that is coated on one side of a 5 mil clear polyester film carrier. This membrane switch spacer comes with a 94# moisture-resistant PCK paper liner. Designed to separate switch circuitry until actuation, Membrane Switch Spacer Single Coated 7997MP provides excellent high temperature resistance (up to 400°F/204°C short-term heat resistance) as well as chemical and UV resistance.

About High Performance Acrylic Adhesive 200MP

3M™ High Performance Acrylic Adhesive 200MP is an industry standard for graphic attachment and general industrial joining applications. It features outstanding adhesion to metal, polycarbonate (PC), ABS and polyester (PET), making it popular across many industries. This adhesive provides some initial repositionability for placement accuracy when bonding to plastics. It also performs well after exposure to humidity and hot / cold cycles, providing confidence that the switch will perform through difficult environmental conditions and millions of actuations.

The Right Choice for a Range of Applications

Membrane switches are found in more and more applications, ranging from farm tractors and medical test systems to microwave ovens and fish finders. 3M has a membrane switch construction suited for the job, with low cost, long life, outstanding environmental performance, and eye-catching graphics.
