Product Description
Membrane Switch Spacer 7956WDL
- 2 mil acrylic adhesive on each side delivers excellent shear strength, resists slippage and edge lifting
- 2 mil white polyester carrier provides strength and stability
- 6 mil double-coated spacer is ideal for withstanding repeated stress of switch actuation
- Adhesive resists oozing at edges and die-cuts for faster part processing
- Double Lay-flat 58 lb. polycoated kraft (PCK) liners add dimensional stability for various die-cutting operations
- Metallized vapor coat on white polyester carrier creates outstanding opacity for graphics
A Top Performer Before, During and After Application
Featuring 3M™ High Performance Acrylic Adhesive 200MP, the 3M™ Membrane Switch Spacer 7956WDL is excellent for graphic applications. Its white 2.0 mil polyester film carrier adds structural strength, and a metallized vapor coating creates outstanding opacity for vivid graphic displays. The adhesive, applied at 2.0 mils on each side of the film, is ideal for the stresses of switch actuation over long periods. It is formulated for excellent shear strength – forming a durable bond with plastics and other smooth surfaces with less oozing at the edges. This allows for easier slitting and die-cutting, faster part processing and minimal waste.
Twin 4.2 mil 58 lb. polycoated kraft (PCK) paper lay-flat liners are designed to cover adhesive consistently for full bonding performance after application. Liners resist curling, tunneling and buckling, increases dimensional stability and holds up even under high humidity for efficient storage and processing. Liner design also enables improved rotary die-cutting at high speeds, as well as improved sheet processing.
Recommended Applications
- Membrane switch spacers
- Graphic and non-graphic applications
- Switch mounting
- Circuit layer assembly
- Metal dome placement
- Lead protection
- Die-cut laminations
Resilient and Ready
3M™ Membrane Switch Spacer 7956WDL is constructed with 2.0 mil high performance acrylic adhesive that is coated on each side of a 2.0 mil white metallized vapor-coated polyester film carrier. This membrane switch spacer is double-linered with twin 4.2 mil, 58 lb. moisture-resistant, lay-flat, PCK paper liners. Designed to separate switch circuitry until actuation, 3M™ Membrane Switch Spacer 7956WDL provides excellent temperature resistance (up to 400⁰F/204⁰C short-term heat resistance), solvents and UV resistance.
About High Performance Acrylic Adhesive 200MP
3M™ High Performance Acrylic Adhesive 200MP is an industry standard for graphic attachment and general industrial joining applications. It features outstanding adhesion to metal, polycarbonate (PC), ABS and polyester (PET), making it popular across many industries. This adhesive provides some initial repositionability for placement accuracy when bonding to plastics. It also performs well after exposure to humidity and hot/cold cycles, providing confidence that the switch will perform through difficult environmental conditions and millions of actuations.
The Right Choice for a Range of Applications
With low cost, long life, outstanding environmental performance and eye-catching graphics, membrane switches are found in more and more applications. They range from farm tractors and medical test systems to microwave ovens and fish finders. Whatever the need, 3M has a membrane switch construction suited for the job.
