Premium 11 mil double-coated membrane switch spacer with High Performance Acrylic Adhesive 200MP for excellent shear strength, edge stability, and reliable performance under repeated switch actuation stress.
The 3M™ Membrane Switch Spacer 7961MP is an 11 mil double-coated spacer engineered for withstanding repeated stress of switch actuation in demanding industrial applications. This premium membrane switch spacer features 3M™ High Performance Acrylic Adhesive 200MP formulated for excellent shear strength, applied at 2.0 mils to each side of a 7.0 mil polyester film carrier. The adhesive resists slippage and edge lifting while providing neat, clean edges for precise slitting and die-cutting operations.
Constructed with a transparent polyester film backing and double-lined with moisture-resistant 58 lb. polycoated kraft (PCK) paper, this spacer provides exceptional dimensional stability and performance under high humidity conditions. The lay-flat liner design enables improved rotary die-cutting at high speeds and efficient sheet processing with minimal waste. This membrane switch spacer delivers outstanding adhesion to metal, polycarbonate, ABS, and polyester surfaces, making it ideal for a wide range of industrial applications including membrane switches, switch mounting, circuit layer assembly, metal dome placement, and lead protection.
With temperature resistance up to 400°F (204°C) short-term heat resistance, excellent solvent and UV resistance, the 3M™ Membrane Switch Spacer 7961MP is built to perform reliably through millions of actuations and difficult environmental conditions. The High-Shear Advantage formulation ensures less oozing at edges, faster part processing, and superior bond performance with plastics and other smooth surfaces. An 18-month shelf life and industrial-grade construction make this spacer the preferred choice for converters and manufacturers seeking consistent, high-quality results.
