A FLIP COVER ASSEMBLY FOR AN APPARATUS HAVING AN APPARATUS HOUSING INCLUDES A CAM MEMBER (14) ROTATABLY ATTACHED TO THE APPARATUS HOUSING, A FLIP COVER (16) ATTACHED TO THE CAM MEMBER (14) FOR ROTATING WITH THE CAM MEMBER (14), AND STRUCTURE (18) FORMED IN THE APPARATUS HOUSING FOR URGING THE CAM MEMBER (14) AND THUS THE FLIP COVER (16) TOWARD ONE OF AN OPEN POSITION AND A CLOSED POSITION IN ACCORDANCE WITH A RELATIVE POSITION OF THE CAM MEMBER (14). THE CAM MEMBER (14) INCLUDES AT LEAST TWO DWELL SURFACES (14A, 14B) DISPOSED ON OPPOSITE SIDES OF A RAISED SURFACE (14C). THE DWELL SURFACES (14A, 14B) ENGAGE THE URGING STRUCTURE IN THE OPEN AND CLOSED POSITIONS, RESPECTIVELY, AND THE RAISED SURFACE (14C) OF THE CAM MEMBER (14)ENGAGES THE URGING STRUCTURE IN AN OPENING/CLOSING POSITION BETWEEN THE OPEN AND CLOSED POSITIONS. THE ARRANGEMENT PROVIDES A POSITIVE "FEEL" FOR THE OPEN AND CLOSED POSITIONS, AND BY USING A CAM MECHANISM, MULTIPLE VARIATIONS ON FLIP COVER (16) FEEL AND MOTION CAN BE ACHIEVED. MOREOVER, THE SIMPLIFIED STRUCTURE REDUCES MANUFACTURING TIME AND COSTS.
