Embodiments of the present disclosure provide an opening and closing mechanism and a leakage protection device. The opening and closing mechanism comprises: a stationary contact and a movable contact, which contacts the stationary contact at ON-position and separates from the stationary contact at OFF-position; a first magnetic assembly; and a second magnetic assembly that is integrally rotatable about an axis, the second magnetic assembly comprising: an electric conductor onto which the movable contact is mounted; and a magnetic body comprising at least one magnetic portion configured to rotate about the axis under a magnetic force from the first magnetic assembly, to correspondingly drive the movable contact to rotate between the ON-position and the OFF-position, wherein a distance from each of the at least one magnetic portion to the axis is smaller than a distance from the movable contact to the axis. In accordance with embodiments of the present disclosure, the transmission efficiency within the opening and closing mechanism may be boosted, and the movable and stationary contacts are separated faster and by a longer distance, so as to improve the performance of the opening and closing mechanism.
