A switch is disclosed in which manual adjustment of a contact spring pileup is avoided by closely controlling the interaction between (1) the contact springs, (2) a movable actuator including a plurality of cam surfaces, each of which is associated with an individual contact spring, and (3) a frame for supporting the actuator. This is achieved by molding a cam follower to one end portion and a mounting element to the other end portion of each contact spring. The mounting elements of the contact springs are positioned in engagement with one another and are secured to the frame. The mounting elements serve to orient the contact springs at a particular angle with respect to one another and accurately locate the contact springs and thereby the cam followers with respect to the cam surfaces of the actuator. The cam followers in combination with the associated cam surfaces serve to locate and provide a predetermined bias to the contact springs.
