A two-way actuator device having a lever with a handle portion near a first end and a bearing portion near a second, opposing end for applying force to a responsive device. Two pivots are provided on the lever and located on opposing sides of the bearing portion. The pivots are biased so that the bearing portion moves in a direction opposite to the handle portion when the handle portion is moved in a first direction and the bearing portion moves in the same direction as a handle portion when the handle portion is moved in a second direction, opposite to the first direction.
