An improved dual flush system for toilets to effect a partial or mini-flush of the toilet to carry away liquid waste by partially opening of the main valve situated in the water holding tank of a toilet for a period of time determined by an operator. The described device provides means to limit the upward lifting of the main valve by limiting the rotational movement of the lever arm connected to the main valve by a cord or chain. Upward movement of the lever arm is limited within the flush handle assembly connecting to the lever arm wherein a partial flush handle movement is terminated by striking a modified eccentrically shaped cam situated within a hollowed out cavity in the partial flush handle, and a full flush handle is provided to continue raising the lever arm to effect a full flush.
