3M Membrane Switch Spacer 7961MP features 3M High Performance Acrylic Adhesive 200MP, formulated for excellent shear strength, on a 7 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.
- 11 mil double-coated spacer is ideal for withstanding repeated stress of switch actuation
- 2 mil acrylic adhesive on each side delivers excellent shear strength, resists slippage and edge lifting
- 7 mil polyester film carrier provides strength and stability
- Adhesive resists oozing at edges and die-cuts for faster part processing
- Layflat 58 lb. polycoated kraft (PCK) liners add dimensional stability for various die-cutting operations

Introducing the 3M Membrane Switch Spacer 7961MP, featuring the advanced 3M High Performance Acrylic Adhesive 200MP. This spacer is specifically designed to withstand the stresses of switch actuation over long periods of time. The adhesive used in this double-sided spacer is formulated to provide excellent shear strength, resulting in a durable bond with plastics and other smooth surfaces. One of the key benefits of this adhesive is that it reduces oozing at the edges, making slitting and die-cutting easier and more efficient. The adhesive is applied at 2.0 mils to each side of a 7.0 mil polyester film carrier, which adds structural strength to the spacer.
The 3M Membrane Switch Spacer 7961MP is equipped with double 4.2 mil 58 lb. polycoated kraft (PCK) paper lay-flat liners. These liners are designed to consistently cover the adhesive, ensuring full bonding performance after application. They resist curling, tunneling, and buckling, providing increased dimensional stability. Even under high humidity conditions, the liners hold up well, making storage and processing more efficient. The liner design also enables improved rotary die-cutting at high speeds and improved sheet processing.
Recommended Applications:- Membrane switch spacers
- Switch mounting
- Circuit layer assembly
- Metal dome placement
- Lead protection
- Die-cut laminations
The 3M Membrane Switch Spacer 7961MP is resilient and ready for various applications. It is constructed with a 2.0 mil high-performance acrylic adhesive that is coated on each side of a 7.0 mil polyester film carrier. The spacer is double-linered with a 4.2 mil, 58 lb. moisture-resistant, lay-flat PCK paper. Designed to separate switch circuitry until actuation, the Membrane Switch Spacer 7961MP offers excellent temperature resistance (up to 400F/204C short-term heat resistance), as well as resistance to solvents and UV rays.
The adhesive used in the 3M Membrane Switch Spacer 7961MP is the 3M High Performance Acrylic Adhesive 200MP. This adhesive is widely recognized as an industry standard for graphic attachment and general industrial joining applications. It exhibits outstanding adhesion to metal, polycarbonate (PC), ABS, and polyester (PET), making it a popular choice across many industries. The adhesive also provides some initial repositionability for precise placement when bonding to plastics. It performs well even after exposure to humidity and hot/cold cycles, ensuring the switch will function reliably in challenging environmental conditions and through millions of actuations.
Membrane switches are becoming increasingly prevalent in a wide range of applications due to their low cost, long life, excellent environmental performance, and visually appealing graphics. They can be found in various products, from farm tractors and medical test systems to microwave ovens and fish finders. Whatever the application, 3M offers a membrane switch construction that is tailored to meet the specific requirements of the job.
