Abstract
An alternate action mechanism in which a rocker makes rolling contact with a surface on a frame, and a plunger is positioned to exert a force toward the surface at a location on the rocker separated from the rolling contact, the force at least initially being along an axis which intersects the surface between limiting positions of the rolling contact. Specially configured leaf springs bias the rocker toward positions corresponding with the limiting positions of the rolling contact.
