The movable body includes a pivot and a contact portion. The pivot is rotatably supported. The contact portion is disposed at a position contactable with a contact piece. The movable body rotates around the pivot and presses the contact piece via the contact portion to move the second contact close to the first contact. The actuator presses the movable body to rotate the movable body around the pivot. The contact piece has a curved portion located between the second contact and the support. The pivot is located on a side where the support is disposed with respect to the curved portion. The actuator includes a pressing member which presses the movable body. The pressing member moves in an axial direction of the pressing member to press the movable body.

The pressing member moves in an axial direction of the pressing member to press the movable body.

The pressing member is configured to move to an off-position and an on-position. When the pressing member is located at the off-position, the first contact and the second contact come into a non-contact state. When the pressing member is located at the on-position, the first contact and the second contact come into a contact state by press of the pressing member against the contact piece. The actuator moves the pressing member from the off-position to the on-position via an overshoot position located beyond the on-position. The contact piece includes a body, and a low rigidity portion having rigidity lower than rigidity of the body. The pressing member presses the low rigidity portion.

The present disclosure relates to a movable contact driving device and a switching apparatus. The movable contact driving device comprises: a contact carrier (10), an electromagnetic actuator (20) and a driving member (30). The driving member (30) is configured to, when the push rod (26) moves to a first predetermined position along the longitudinal axis, rotate relative to the push rod (26) in a first direction such that the driving member (30) engages a fixed portion of the electromagnetic actuator (20) to lock the contact carrier (10) in a position corresponding to a closed position of the movable contact (40); and, when the push rod (26) moves to a second predetermined position along the longitudinal axis, rotate relative to the push rod (26) in a second direction opposite the first direction such that the driving member (30) is unlocked from the fixed portion of the electromagnetic actuator (20) to allow the contact carrier (10) to move to a position corresponding to an open position of the movable contact (40).
