摘要： 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.
