Methods and apparatus for reducing bounce between contacts

摘要

A contact assembly includes a stationary contact (14) having a first contact surface (30). At least a portion of the first contact surface (30) defines a wiping contact surface. The contact assembly also includes a movable contact (12) having a second contact surface (32) defining a contact area (36) that engages the first contact surface (30). The movable contact (12) is movable along a driving path (A) toward the stationary contact (14) possibly by passing a current through a coil (16), and the movable contact (12) is moved along a second path (B) different from the driving path (A) after initial impact with the stationary contact (14). The stationary contact (14) is oriented or shaped with respect to the movable contact (12) such that the movable contact (12) engages, and wipes against, at least a portion of the wiping contact surface of the first contact surface (30) when the movable contact (12) is moved along the second path. A method of closing the contact assembly is also disclosed.
