Abstract
A keyboard assembly having a keyboard membrane and a set of electrical connections. The keyboard membrane includes conductors arranged on the membrane to convey electrical signals generated by depression and/or release of keyboard keys to electrical terminals affixed to the membrane. The electrical connections are made between the membrane terminals and corresponding mutually-opposing terminals of a printed circuit board affixed within the body of the keyboard. The connections are arranged in first and second linear rows. The first row of connections is arranged at a uniform spacing in a direction approximately parallel to a long dimension of the membrane. The connections of the second row are arranged at a uniform spacing in a direction approximately perpendicular to the long dimension. An inter-terminal pitch among the connections of the first row is substantially greater than a inter-terminal pitch among the connections of the second row.
