3M Membrane Switch Spacer 7953MP features 3M High Performance Acrylic Adhesive 200MP, formulated for excellent shear strength, on a .5 mil PET carrier. This adhesive withstands repeated switch actuation and forms neat, clean edges for precise slitting and die-cutting. Double PCK paper liners resist humidity, curling, tunneling and buckling, and add stability for improved sheet processing.

  • 3.5 mil double-coated spacer is ideal for withstanding repeated stress of switch actuation
  • 1.5 mil acrylic adhesive delivers excellent shear strength, resists slippage and edge lifting
  • .5 mil polyester film carrier provides strength and stability
  • Adhesive resists oozing at edges and die-cuts for faster part processing
  • Lay-flat polycoated kraft (PCK) liners add dimensional stability for various die-cutting operations

A Top Performer Before, During and After Application

3M™ Membrane Switch Spacer 7953MP is an ideal solution for switch actuation over long periods. It features 3M™ High Performance Acrylic Adhesive 200MP, which is formulated for excellent shear strength. This double-sided spacer forms a durable bond with plastics and other smooth surfaces with less oozing at the edges. This allows for easier slitting and die-cutting, faster part processing, and minimal waste. The adhesive is applied at 1.5 mils to each side of a .5 mil polyester film carrier, which adds structural strength.

Double 4.2 mil 58 lb. polycoated kraft (PCK) paper lay-flat liners are designed to cover adhesive consistently for full bonding performance after application. Liners resist curling, tunneling, and buckling, increase dimensional stability, and hold up even under high humidity for efficient storage and processing. Liner design also enables improved rotary die-cutting at high speeds, as well as improved sheet processing.

Recommended Applications
  • Membrane switch spacers
  • Switch mounting
  • Circuit layer assembly
  • Metal dome placement
  • Lead protection
  • Die-cut laminations
Resilient and Ready

3M™ Membrane Switch Spacer 7953MP is constructed with 1.5 mil high performance acrylic adhesive that is coated on each side of a .5 mil polyester film carrier. This membrane switch spacer comes double-linered with a 58 lb. moisture-resistant, lay-flat, PCK paper. Designed to separate switch circuitry until actuation, 3M™ Membrane Switch Spacer 7953MP provides excellent temperature resistance (up to 400⁰F/204⁰C short-term heat resistance), solvents, 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. Whatever the need, 3M has a membrane switch construction suited for the job. With low cost, long life, outstanding environmental performance, and eye-catching graphics, 3M™ Membrane Switch Spacer 7953MP is the right choice for a range of applications.
