Abstract
A dial keypad is provided for use with a mobile device having a keyboard. The keypad has a push-through, hinge-spring design that activates only one of two keyboard keys underlying a dial key and allows backlighting transmissivity. A translucent material can be used to allow the keyboard key backlighting to be coupled through to a top dial key. The keypad creates an aesthetically balanced dial keypad arrangement over a QWERTY keyboard. A preferable mechanical implementation allows backlighting and has an offset contact and spring design to activate one of the two underlying keys. This activation simplifies the software implementation for executing the dial number since the signal is coming from one address rather than having to make a determination of whether it is coming from one or two addresses. Moreover, the resulting dial key press has a standard single click feel.
