Abstract
Abstract An integral electric switch, for controlling an electronic apparatus, comprises a main housing and a flap portion, rotatably attached thereto. The main housing contains the electronic apparatus. The flap portion has a hinge cam for rotatably attaching the flap portion to the main housing, so that the flap portion is movable from a defined open position to a closed position with respect to the main body. The main housing comprises a plurality of spring fingers making sliding contact with the hinge cam as the flap portion is rotated from the open position to the closed position thus providing a switching function and electrical connection from the housing to devices contained within the flap.
