Memtron’s Uni-Layer construction provides the lowest cost solution available in membrane switch technology. By consolidating all of the trace work onto a single membrane layer, every trace can be terminated through a single wiper ZIF or friction-fit connection.

Attributes - polyester membrane

• Suitable for switch applications with low key density and/or generous spacing
• Actuation forces from 10 to 30 ounces depending on dome size and spacer configuration
• Typical actuation forces are 15 +/- 3 ounces
• 2,000,000 actuation life expectancy
• Conducive to ring or full key embossing
• Single tail layer is ideal for ZIF or friction-fit connectors
• Suitable for Polyester, Polycarbonate, and Elastomeric overlays
• Operating temperature range of –40 to +85 C and storage temperature range of –40 to +85 C
• Integration into both flex circuit and PCB constructions

Attributes - printed circuit board

• An efficient design for most keypad programs regardless of key density
• Offers significant cost savings by combining a membrane switch keypad and a printed circuit board into one common assembly
• False entry is eliminated since the stainless steel dome is in direct contact with the PCB circuitry
• A variety of stainless steel dome sizes and options are available
• Actuation forces from 10 to 30 ounces depending on dome size and spacer configuration
• Typical actuation forces are 15 +/- 3 ounces
• Suitable for Polyester, Polycarbonate, and Elastomeric overlays
• 2,000,000 actuation life expectancy
• Conducive to ring or full key embossing
• Operating temperature range of –40 to +85 C and storage temperature range of –40 to +85 C
