3M™ Membrane Switch Spacer 7956MP is a high-performance spacer designed for demanding switch applications. It features the 3M™ High Performance Acrylic Adhesive 200MP, known for its excellent shear strength and durability. This adhesive is applied on both sides of a 2 mil PET film carrier, ensuring reliable performance in repeated switch actuation scenarios.
- High Performance Adhesive: The 3M™ High Performance Acrylic Adhesive 200MP offers excellent shear strength, forming durable bonds with plastics and other smooth surfaces. This minimizes oozing at the edges, allowing for precise slitting and die-cutting.
- Durable PET Film Carrier: The 2 mil polyester film carrier adds structural strength, enhancing the spacer's ability to withstand repeated switch actuation.
- Double PCK Paper Liners: Double 4.2 mil 58 lb. polycoated kraft (PCK) paper liners provide consistent coverage of the adhesive, resisting humidity, curling, tunneling, and buckling. This improves dimensional stability and facilitates efficient storage and processing.
- Enhanced Processing: The liner design allows for improved rotary die-cutting at high speeds and enhanced sheet processing, making it ideal for high-volume production environments.
Recommended Applications:
- Membrane switch spacers
- Switch mounting
- Circuit layer assembly
- Metal dome placement
- Lead protection
- Die-cut laminations
Usage and Maintenance: Ensure surfaces are clean and dry before applying the membrane switch spacer. Apply with firm pressure to achieve maximum adhesion. Store the product in a cool, dry place away from direct sunlight to maintain its properties. The high-performance adhesive and durable liners make this spacer suitable for long-term use in demanding switch applications.
