Breaking mechanism for switchgear and switchgear

The invention discloses a breaking mechanism for a switch device and the switch device. The breaking mechanism comprises: a housing; the driving disc is pivotally arranged on the shell; the first microswitch is connected in a control circuit of the motor and drives the motor to operate when being excited; the second microswitch is connected in a control circuit of the motor and switches the running direction of the motor when being excited; the first actuating piece is pivotally arranged on the shell and is configured to move between a first state and a second state when being driven by the driving disc during pivoting of the driving disc, in the first state, the first actuating piece excites the first microswitch, and in the second state, the first actuating piece does not excite the first microswitch; and the second actuating piece is pivotally arranged on the shell and is configured to move between a third state and a fourth state when being driven by the driving disc during pivoting of the driving disc, i
