3M's single-coated membrane switch spacers are ideal for circuit layers, metal dome placement, and lead protection. The 3M high-performance acrylic adhesive 200MP provides the assurance necessary for constructing durable, long-lasting membrane switches.
Features
- Smooth adhesive layer for consistent actuation and excellent sealability of switch
- High-adhesive strength to resist moisture penetration and environmental conditions
- High-cohesive strength to resist lifting and separation especially in harsh environments
- Easy liner release for fast, consistent processing
- High-temperature resistance to resist splitting in harsh environments
- High chemical resistance to resist contamination of contacts in harsh environments
- Heat-stabilized polyester for dimensional stability through broad temperature range
- Moisture stable liners for easy, lay-flat processing
Applications
- Add a different thickness of adhesive to one side of a membrane switch to build a membrane switch spacer
- Designed for use as a substrate for membrane-switch circuitry
- Hold metal domes in place
- Protect conductive leads
