Premium 6 mil double-coated membrane switch spacer with metallized vapor coat, white polyester carrier, and high-performance acrylic adhesive for industrial switch applications requiring exceptional durability and precision.
The 3M™ Membrane Switch Spacer 7956MWS is a premium industrial-grade double-coated adhesive spacer specifically engineered for membrane switch applications. This professional-quality product features a 2 mil white polyester film carrier with metallized vapor coating that provides exceptional opacity for graphic applications. The spacer is designed to separate switch circuitry until actuation, making it ideal for applications requiring reliable performance through millions of actuations. With dimensions of 48 inches width by 180 yards length and a total thickness of 6 mil, this product comes as a single roll per case and is equipped with a lay-flat 58# polycoated kraft paper liner for enhanced dimensional stability.
Featuring 3M's High Performance Acrylic Adhesive 200MP applied at 2 mil thickness on each side of the carrier, this membrane switch spacer delivers outstanding shear strength and excellent adhesion to metals, polycarbonate, ABS, and polyester surfaces. The adhesive formulation resists oozing at edges and die-cuts, enabling faster part processing and minimal waste. The product offers excellent temperature resistance up to 400°F/204°C for short-term heat exposure and maintains performance down to -40°F, with an 18-month shelf life ensuring long-term storage viability.
This industrial-grade spacer is ideal for a wide range of applications including membrane switch spacers, graphic and non-graphic applications, switch mounting, circuit layer assembly, metal dome placement, lead protection, and die-cut laminations. The PCK paper liner resists humidity, curling, and tunneling, while maintaining dimensional stability even under high humidity conditions. The product is specifically designed for industrial and occupational use only and is not intended for consumer sale or use.
