Abstract
For a telephone handset, a rigid chassis is provided, of elongate form with positions at each end for mounting respectively a receiver and a transmitter and an intermediate position for a pushbutton dial. A flexible circuit member carries the majority of the various components for the handset. The flexible circuit is elongated and extends along the back of the chassis, down through a slot and back along the front of the chassis, with the pushbutton dial assembly attached to the flexible circuit member. The majority of the items such as electronic components, recall button, line cord jack and other components can be preassembled to the flexible circuit member which is then assembled to the chassis, followed by attachment of the pushbutton dial assembly.
