Break mechanism for switching apparatus and switching apparatus

A break mechanism for a switching apparatus, comprising:

• a contact driving assembly comprising a driven part and coupled to a moving contact to drive the moving contact to move between an open position and a closed position;
• a handle assembly adapted to rotate around a pivot shaft and comprising a relevant driving part and a telescopic driving part which is telescopic, the telescopic driving part adapted to be coupled with the driven part, and keeping a length unchanged during a rotation of the handle assembly in a first rotation direction to drive the contact driving assembly to rotate in a second rotation direction opposite to the first rotation direction, thereby driving the moving contact to move from the open position to the closed position, and the telescopic driving part being adapted to retract during a rotation of the handle assembly in the second rotation direction to avoid the driven part;
• and
• an auxiliary assembly coupled to the relevant driving part, and adapted to move from a first position to a second position in a first movement direction during tripping of the switching apparatus, thereby causing the handle assembly to rotate in the second rotation direction.
