    • A magnetic flux field momentarily produces a first reed switch mode upon movement of a permanent magnet to a selected position and aspect in response to depression of a self-restoring manual member. Thereafter, during the depressing stroke, a spring which had been tensioned in response to depression of the manual member is released from a restraint. The untensioning force snaps the magnet to another aspect to effect a second reed switch mode. Cam means comprising the spring restraint also enables return of the permanent magnet from its end stroke position to its start stroke position without change of aspect, whereby the second mode of the reed switch is maintained.
    • 当永久磁铁移动到选择的位置和方面时,响应于自恢复手动构件的按压,磁通场瞬间产生第一舌簧开关模式。 此后,在按压行程期间,响应于手动构件的按压而张紧的弹簧从限制释放。 未张紧力将磁体锁定到另一方面以实现第二簧片开关模式。 包括弹簧约束的凸轮装置还能够使永磁体从其末端行程位置返回到其起始行程位置而不改变方面,由此保持簧片开关的第二模式。

    • An opening assembly is provided for an electrical switching apparatus having a housing, separable contacts enclosed by the housing, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a poleshaft. The opening assembly includes a spring link comprising a first portion structured to be pivotably coupled to the poleshaft, and a second portion disposed generally opposite of the first portion. A number of opening springs each include a stationary end coupled to the housing, and a movable end coupled to the second portion of the spring link. The spring link is movable between an open position, wherein the opening springs bias the spring link and poleshaft to maintain full separation of the separable contacts, and a closed position, wherein the opening springs either do not bias the poleshaft or bias the poleshaft with a low level of torque.

    • A trip latch assembly is provided for an electrical switching apparatus, such as a circuit breaker. The circuit breaker operating mechanism includes a pole shaft. The trip latch assembly includes a trip latch pivotably coupled to the circuit breaker housing and being movable between a latched position and an unlatched position. A trip latch reset spring is structured to bias the trip latch toward the latched position. A spring housing at least partially overlays the trip latch reset spring. A trip latch spring link includes a first end movably coupled to the pole shaft, and a second end cooperating with the spring housing. When the circuit breaker needs to be reset, the trip latch spring link engages the spring housing, in order apply torque to the trip latch reset spring. When the circuit breaker is closed, the bias of the trip latch reset spring on the trip latch is removed.
    • 提供了一种用于诸如断路器的电气开关装置的跳闸闩锁组件。 断路器操作机构包括极轴。 跳闸闩锁组件包括可枢转地联接到断路器壳体并可在锁定位置和解锁位置之间移动的跳闸闩锁。 行程闩锁复位弹簧被构造成将跳闸闩锁偏压到锁定位置。 弹簧壳体至少部分地覆盖跳闸闩锁复位弹簧。 跳闸闩锁弹簧连杆包括可移动地联接到极轴的第一端和与弹簧壳体配合的第二端。 当断路器需要复位时,跳闸闩锁弹簧连杆与弹簧壳体接合,以便将跳闸锁定复位弹簧施加扭矩。 当断路器闭合时,跳闸闩锁上的跳闸闩锁复位弹簧的偏置被去除。
