Non-Tactile Membrane Switchmembrane switch

A non-tactile Membrane switch is typically constructed as two circuit layers separated by a spacer.  The top and bottom layer can both have circuit patterns that are shorted together, or one layer of circuitry where interlocking “fingers” or electrically connected by a shorting bar. There is no tactile or “click” as part of the actuation.  Because there is no tactile response, it is common for the application to have an audible response such as a beep, or a light so the operator is aware that the contact has been made.


GDSI specializes in the design and manufacture of membrane switches that need to withstand harsh environments or require a higher level of reliability than typical silver on polyester switches.
We can use a variety of circuit configurations and materials that are proven to last longer and perform more reliably  Some of these options include:

  • Completely sealed switches
  • D/SPC ® - Unique circuit technology eliminates problems associated with cross over polymer circuitry.
  • Double and single sided copper circuitry
