SWITCH UNDER LOAD FOR STEPPED SWITCH UNDER LOAD AND PERMANENT MAIN SWITCH AND DISCONNECTOR THEREFOR Russian patent published in 2020 - IPC H01H9/00 

FIELD: physics.

SUBSTANCE: switch (10) for switch (11) under load of stepped switch under load, containing contact (13) of branch; primary fixed contact (14); secondary fixed contact (15); primary movable contact (16), which is installed relative to contact (13) of branch and primary fixed contact (14) with possibility of such rotation around rotary axis (21), that it can receive first end position, in which it by means of the first adjacency point adjoins the branching contact and by means of the second adjacency point adjoins the primary fixed contact, and a second end position, in which it is separated from said contacts; secondary movable contact (17), which is installed relative to contact (13) of branch and secondary fixed contact (15) with possibility of rotation around rotary axis (21) so that it can receive first end position, in which it by means of the third adjacency point adjoins the branching contact and by means of the fourth adjacency point adjoins the secondary fixed contact, and the second end position, in which it is separated from these contacts.

EFFECT: technical result is to increase punching strength of switch under load.
