摘要： A mechanism for the rapid closure of electrical contacts on a modular electrical apparatus includes movable electrical contacts that pivot with respect to a rotatable contact support and are maintained in a rest position by springs. A manually actuated control lever imparts opposing rotary movements to the control lever and the movable contacts. A cam, driven by the control lever, and a finger attached to each movable contact move in paths that intersect when the movable contacts are separated from the fixed contacts. The cam and finger are locked during a portion of control lever rotation before it reaches a stable position wherein the fixed and movable contacts are closed. The contact support continues to travel while a contact spring accumulates energy, which is dissipated only when the cam and finger separate. During a final stage of motion of the control lever, the cam freely rotates relative to the control lever, with its range of motion being limited only by a stop element on the cam.
