Rubber Keypads Switch
In some applications it is preferred to have a rubber keypad for the user interface rather than a membrane switch graphic. Tortai offers multiple construction options when a rubber keypad overlay is required.
Conductive Carbon Puck Elastomer Over Printed Circuit Board
This construction provides tactile feedback from the elastomer and the carbon puck serves as the shorting element for traces on a printed circuit board. |

Non-Conductive, Tactile Elastomer Over Sealed Membrane
This construction provides tactile feedback from the elastomer. Printed shorting pads on the membrane switch serve as the shorting element for traces on a printed circuit board. The membrane switch is sealed, which is an advantage since the rubber elastomer is porous and oils can penetrate. |

Non-Conductive, Non-Tactile Elastomer Over Sealed Tactile Membrane
This construction provides tactile feedback from polyester domes. All of the switching is part of the sealed membrane switch with circuitry exiting via a circuit tail. Having tactile in the Poly Dome allows for a thinner construction when compared to a tactile elastomer. |
