Dual silicone keypad actuation
First Claim
1. A radio for use in automotive applications, the radio comprising;
- a trimplate having an inner surface and an outer surface;
a pod assembly capable of coupling and uncoupling with said outer surface of said trimplate, said pod assembly having a first silicone keypad secured between a front body and a back panel, said first silicone keypad having a plurality of silicone keypad buttons, wherein said pod assembly is capable of movement between a first position and a second position;
a printed circuit board assembly coupled with a portion of said inner surface of said trimplate; and
a second silicone keypad between said trimplate and said printed circuit board assembly, said second silicone keypad having a plurality of silicone domes, each of said plurality of silicone domes having at least one carbon contact in closest proximity to said printed circuit board assembly and a top portion in closest proximity with one of said plurality of silicone keypad buttons, wherein said second silicone keypad is capable of movement between a third and fourth position.

Abstract
A radio having a detachable pod assembly and a pair of silicone keypads. The first silicone keypad is located within the detachable pod assembly, while the second silicone keypad is closely coupled with a printed circuit board that is electrically coupled with a microprocessor based controller. When the pod assembly is snapped into the radio faceplate, there is preferably a 0.2 mm interference fit between the two silicone keypads. When the user depresses the first silicone keypad, the actuation forces depress the second silicone keypad in series. As the second silicone keypad is depressed, a carbon contact “pill” on the second silicone keypad contacts the printed circuit board and signals the circuit board'"'"'s microprocessor that a button has been depressed. The microprocessor then directs the radio to respond accordingly.
