Premium 11 mil double-coated membrane switch spacer with high-performance acrylic adhesive, polyester film carrier, and moisture-resistant kraft paper liners for industrial applications
The 3M™ Membrane Switch Spacer 7961MP is a premium double-coated adhesive spacer specifically engineered for membrane switch applications requiring exceptional durability and precision. This 11 mil spacer features 3M™ High Performance Acrylic Adhesive 200MP applied at 2 mil thickness on each side of a robust 7 mil polyester film carrier, delivering outstanding shear strength and resistance to slippage and edge lifting. The innovative double-lined construction with 4.2 mil, 58 lb. polycoated kraft paper liners provides superior dimensional stability, moisture resistance, and excellent performance during high-speed rotary die-cutting operations.
Designed to withstand the repeated stress of switch actuation over extended periods, this membrane switch spacer excels in demanding industrial applications ranging from farm tractors and medical test systems to microwave ovens and fish finders. The adhesive formulation offers excellent temperature resistance up to 400°F (204°C) for short-term heat exposure, combined with outstanding solvents and UV resistance. The lay-flat liner design resists curling, tunneling, and buckling while maintaining consistent adhesive coverage for full bonding performance after application.
This product comes in convenient 50 sheet/case packaging with dimensions of 24 inches width by 36 yards length, making it ideal for high-volume manufacturing and die-cutting operations. The adhesive's low oozing characteristics at edges enable faster part processing with minimal waste, while forming neat, clean edges for precise slitting and die-cutting. Perfect for membrane switch spacers, switch mounting, circuit layer assembly, metal dome placement, lead protection, and die-cut laminations in industrial and occupational settings.
