Abstract

A compact, ergonomic telephony keypad is described which comprises three principle buttons capable of performing twelve distinct electronic switch operations. The three principle buttons are positioned in a group comprising a telephony keypad with each button formed for tactile manipulation to achieve four of the twelve switch operations. Each button also has four tactile depressible areas positioned thereon around an imaginary central axis. The four tactile depressible areas are spaced about equally apart around the imaginary central axis of each of the principle buttons. And, the three principle buttons are spaced apart and positioned relative to each other so as to substantially maximize the spacing of the twelve depressible areas, while, substantially minimizing the spacing of the principle buttons.
