Abstract
A multiple input key for inputting characters and the key has a body with a top and bottom surface, with the bottom surface being proximal to a printed circuit board and the top surface being distal from the printed circuit board. The key is pivotable about a pivot. A pivot extends from the bottom surface of the body and has an electrical contact pad such that when the contact pad contacts one of the leads on the printed circuit board a circuit is closed. A skirt surrounds the periphery of the body of the key and the skirt operatively supports the body of the key on the printed circuit board.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
