摘要： Apparatus and associated methods relate to sequentially opening and/or closing a plurality of switches. A rotational securing assembly sequentially secures and releases a plurality of indexing members (78a-h) evenly distributed along a circular path centered on an axis of rotation of the rotatable disk (74), thereby sequentially securing and releasing the rotatable disk (74) to and from a sequence of rotational positions. A ratcheting assembly sequentially engages a plurality of advancing members of the rotatable disk (74), thereby sequentially rotating the rotatable disk (74) to a next one of the sequence of rotatable positions. A cam coupled to the rotatable disk (74) sequentially either opens or closes a plurality of switches attached to an annular frame and distributed along a second circular path centered on the axis of rotation. Operations of the rotational securing assembly are coordinated with those of the ratcheting assembly so as to advance rotation of the rotatable disk (74) in a stepwise fashion.

摘要： The present invention relates to the field of low-voltage electrical appliances, in particular to an operating mechanism of a switch apparatus, a transmission shaft, a cam and an operating shaft are rotationally arranged, respectively, the operating shaft drivingly cooperates with the cam to drive it to rotate, and an energy-storage spring cooperates with the cam; the cam rotates to enable the energy-storage spring to store energy, the energy-storage spring stores energy to a maximum value when the cam rotates to a dead-center position, and the energy-storage spring releases energy to drive the cam to rotate after the cam rotates to pass through the dead-center position; the transmission shaft drivingly cooperates with the cam and is used to output a driving force to a moving contact structure of the switch apparatus, so as to enable the switch apparatus to make contact or break contact; a rotational allowance is set between the cam and the transmission shaft, so that the transmission shaft remains stationary in a process of the cam rotating to the dead-center position; after the cam rotates to the dead-center position, it continues to rotate through the first angle ϕ1, so as to contact with the transmission shaft to drive it to rotate, wherein the first angle ϕ1>0°; the operating mechanism has simple structure and fast operation speed of break-contact and make-contact. The present invention also provides a switch apparatus comprising the operating mechanism having fast operation speed of break-contact and make-contact and high current-carrying capacity.

摘要： A switching apparatus (1) for medium voltage electric systems, said switching apparatus comprising one or more electric poles (2), wherein, for each electric pole, said switching apparatus comprises:
- a first pole terminal (11), a second pole terminal (12) and a ground terminal (13), said first pole terminal (11) being electrically couplable with a first conductor of an electric line, said second pole terminal (12) being electrically couplable to a second conductor of said electric line and said ground terminal (13) being electrically couplable to a grounding conductor;
- a first fixed contact member (5A) and a first movable contact member (6A), said first fixed contact member being electrically connected to said first pole terminal (11) and including a first fixed contact (5), said first movable contact member (6A) being electrically connected to said second pole terminal (12) and including a first movable contact (6), said first movable contact member (6A) being reversibly movable about a corresponding first rotation axis (A1);
- a second fixed contact member (8A) and a second movable contact member (9A), said second fixed contact member (8A) being electrically connected to said first pole terminal (11) and including a second fixed contact (8), said second movable contact member (9A) including a second movable contact (9) and being reversibly movable along a corresponding translation axis (A);
- a vacuum chamber (10), in which said second fixed contact (8) and said second movable contact (9) are enclosed and can be coupled or decoupled;
- a motion transmission mechanism for actuating said second movable contact member.
