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.
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
Information dense I/O devices
Noise sensitive environments
Tightly controlled actuation experience
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.
To hear the noise level at actuation, request your polyester dome membrane switch sample packet.
