SWITCHING DEVICE ARRANGEMENT Russian patent published in 2017 - IPC H01H33/12 

FIELD: electricity.

SUBSTANCE: switching device includes the first contact group (11), as well as the second contact group (12). The first contact group (11) has the first electric arc contact element (15), as well as the first contact element (13) of the rated current. The first contact element (13) of the rated current can be moved relative to the first electric arc contact element (15). The first transmission mechanism is used in the kinematic chain to create the relative motion of the first rated current contact element (13) and the first electric arc contact element (15). The first transmission mechanism has a kinematic connection between the fixed counter-support (31, 33, 33a) and the first electric arc contact element (15).

EFFECT: secure relative movement of the contact group.
