Polyester Dome Membrane Switch

A polyester dome membrane switch gives you the ability to design high density membrane keypads at a lower cost than a traditional metal dome membrane switch.  Formed during a single stage thermal cycle, polyester dome membrane switches are three dimensional tactile buttons formed of molded PET.

Polyester Dome Membrane Switch Benefits

  • Highly accurate tooling allows actuation force to be tightly specified
  • The “softer” actuation is extremely quiet
  • Can achieve higher keypad densities than metal dome membrane switches
  • Can be a lower cost method to produce a high density I/O device

Polyester Dome Membrane Switch Applications

  • Information dense I/O devices
  • Noise sensitive environments
  • Tightly controlled actuation experience
  • Medical devices
  • Industrial
  • Consumer electronics

Polyester Domes Give Actuation Control

You specify the actuation force of your polyester dome membrane switch.  Actuation force is determined by switch geometry which can be reliability manufactured at tight tolerances from prototype through high-volume production runs.

The ability to tightly control the actuation force is a unique quality of a polyester dome membrane switch.  The range of actuation specification is much wider than can be supplied by a traditional metal dome membrane switch where actuation force is determined by standard metal dome under-pads.

Ideal for Quiet Environments

An electronic interface using polyester dome switches delivers a much quieter experience.   A polyester dome membrane switch lacks the “click” sound delivered by metal dome switches.  This makes polyester dome membrane switches ideal for noise sensitive environments such as hospitals and recording studios.
