GROUP OF KEYING ACTION MEMBERS FOR THE SWITCH, HAVING AN INTERNAL COMPACT DESIGN Russian patent published in 2022 - IPC H01H1/42 

FIELD: electrical engineering.

SUBSTANCE: invention relates to a group (31, 32) of keying action members for a switch, a two-position switch, a disconnector or, in general, a power switch. The power switch (1) is installed inside the insulated housing (2) of the switch and contains at least a movable contact (29) providing an electrical connection, while the group (31, 32) of keying action members is made with the possibility of gripping the specified at least movable contact (29) of the specified power switch (1), and the modular design contains many pincer-like elements (60) mounted in parallel on the support frame (46) and, in turn, containing the corresponding contact fingers (45), moving in an angular direction relative to each other, which mutually converge and diverge against the action of the elastic return means (47).

EFFECT: providing a compact design of the internal movable contacts of the switch and providing the switch with higher reliability and a long service life.
