Abstract

Embodiments of the present disclosure provide a press type mechanical switching mechanism and a circuit breaker. The switching mechanism comprising: a first and a second mechanical contact capable of switching between an on state and an off state; a first pressing member configured to switch the first and second mechanical contacts from the off state to the on state in a case that the first and second mechanical contacts are in the off state and the first pressing member is pressed down; a second pressing member configured to switch the first and second mechanical contacts from the on state to the off state in a case that the first and second mechanical contacts are in the on state and the second pressing member is pressed down; an electromagnetic assembly configured to switch the first and second mechanical contacts from the on state to the off state in a case that the first and second mechanical contacts are in the on state and the first pressing member is not pressed down and in a case that the first and second mechanical contacts are in the on state and the first pressing member is kept pressed down.
