    摘要： The present invention discloses a change-over contact piece assembly, comprising: a first stationary contact piece with a first stationary contact provided thereon; a second stationary contact piece with a second stationary contact provided thereon; and a movable contact piece assembly comprising: a movable contact carrier connectable to a rotary member; a movable contact fixed on the movable contact carrier; and a reset member, with one end thereof being connected to the movable contact carrier, and the other end thereof being connected to the rotary member, wherein as the rotary member rotates, the movable contact can be driven into contact with the first stationary contact or the second stationary contact. The present invention further provides an auxiliary switch having the above-mentioned change-over contact piece assembly. With the change-over contact piece assembly of the present invention, it can be ensured that the movable contact carrier applies the same contact piece pressure to stationary contact pieces on upper and lower sides, thereby ensuring the stability of electrical contact between the movable contact and the stationary contacts.

    摘要： The present disclosure relates to a structure of a crossbar 20 for a manual motor starter, MMS, 100 in which a function of an auxiliary lever (2) is performed by the crossbar to thus reduce the number of components and operational errors. The crossbar 20 is connected to an operating mechanism (10) and an auxiliary contact lever 30 operates an auxiliary contact 40, wherein a pressing unit 25 is formed in the crossbar 20 to operate the auxiliary contact lever 30 upwardly.

    摘要： The invention relates to a switching device comprising a base module (1) equipped with an electromagnetic drive, which comprises a yoke (20), a coil (19) and an armature (21) arranged in a movable manner relative to the yoke (20), and a switching contact. The switching contact comprises a stationary switching piece and a movable switching piece arranged opposite the stationary switching piece, and the switching contact can be switched between an "open" position and a "closed" position by means of a movement of the armature (21). The switching device also comprises a modular auxiliary switching unit (9) equipped with a contact system consisting of a stationary switching piece and a movable switching piece arranged opposite the stationary switching piece. The invention is characterized in that the coupling between the base module (1) and the modular auxiliary switching unit (9) is designed such that different distances in the contact system of the auxiliary switching unit (9) can be transferred during a trigger event by means of an elastic element regardless of the auxiliary switching unit (9) being used.
