Scotch Single-Side Membrane Switch Spacer 7993MP


Single-side spacers aid in the construction of membrane switch circuitry by protecting leads, holding domes in place, or building a custom spacer


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.

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
