Abstract
A portable communication device is disclosed comprising a front face (3) having a plurality of openings therein, and an array (6) of keys. Each key has a switch actuator, a switching element, and coupling means. The switch actuator has an upper surface bounded by side walls, and the switch actuator of each key of the array (6) protrudes from one of the plurality of openings to provide its upper surface for tactile actuation by a user and is physically discrete from the others. The coupling means couples the tactile actuation of the upper surface by a user to the switching element.
