MINIATURE CIRCUIT BREAKER OPERATING MECHANISM Russian patent published in 2020 - IPC H01H71/10 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical equipment. Miniature switch comprises: a handle, a drive connecting rod, fixed and movable contacts, a tension spring and a disconnecting lever. One end of drive connecting rod is pivotally connected to handle, and other end is conjugated with movable contact. One end of tension spring is fixed on housing, and other end is connected to movable contact, which is driven by tension spring and drive connecting bar to create contact pressure and force of elastic expansion for closing contacts, and tension spring creates elastic force of accumulated energy for opening contacts. Switching lever is arranged on the movable contact and is used to control the locking and unlocking interaction between the drive connecting rod and the movable contact. At automatic disconnection, the disengaging lever disconnects the drive connecting rod from the movable contact for automatic disengagement of the working mechanism.

EFFECT: technical result consists in simplification of design, reduction of costs for production, increased efficiency of production and optimization of mechanical parameters of operation.
