3M™ Membrane Switch Spacer 7957MP features 3M™ High Performance Acrylic Adhesive 200MP, formulated for excellent shear strength, on a 3 mil PET film 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.

The High-Shear Advantage – Less Oozing and Tighter Edges
Featuring 3M™ High Performance Acrylic Adhesive 200MP, our 3M™ Membrane Switch Spacer 7957MP is ideal for the stresses of switch actuation over long periods. The adhesive on this double-sided spacer is formulated for excellent shear strength – forming 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 2.0 mils to each side of a 3.0 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 7957MP is constructed with 2.0 mil high performance acrylic adhesive that is coated on each side of a 3.0 mil polyester film carrier. This membrane switch spacer comes double-linered with a 4.2 mil, 58 lb. moisture-resistant, lay-flat, PCK paper. Designed to separate switch circuitry until actuation, our Membrane Switch Spacer 7957MP provides excellent temperature resistance (up to 400?F/204?C short-term heat resistance), solvents and UV resistance.

About Our High Performance Acrylic Adhesive 200MP
3M™ High Performance Acrylic Adhesive 200MP is considered 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
With low cost, long life, outstanding environmental performance and eye-catching graphics, membrane switches are found in more and more applications. They range 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.

Bringing Better Ideas to the Surface through Science
In our 3M Industrial Adhesives and Tapes Division, we apply the science of adhesion to deliver innovative solutions that improve the design and manufacturing processes of companies around the world. In the end, our technologies help customers like you deliver competitive products to the market faster and more efficiently.
