OPERATION MECHANISM AND SWITCH DEVICE

WIPO Patent Application WO/2023/241491

A1

The present invention relates to the field of low-voltage electric appliances, in particular to an operation mechanism and a switch device comprising same. When opening the operation mechanism, an operation shaft drives an energy storage rotary disc and a transmission plate at the same time; the transmission plate moves from a transmission plate closed position to a transmission plate breaking position; the energy storage rotary disc drives an output shaft structure to rotate from an output shaft closed position to an output shaft breaking position; after a first spring starts to release energy, the energy storage rotary disc drives the output shaft structure to rotate to a breaking transition position and is disengaged from the output shaft structure after driving same to cross the breaking transition position, and meanwhile, the output shaft structure and the transmission plate cooperate to enable a second spring group to start energy release after energy storage is completed; and the second spring group releases energy to drive the output shaft structure to rotate to said output shaft breaking position. The operation mechanism and the switch device of the present invention can remarkably increase the clearance between a moving contact and a fixed contact when they are open.
