A rotary dual breakpoint moving contact module, comprising: a single-phase independent rod-shaped block rotor having a first through hole at the center thereof, a first recess and two semicircle slot holes on each axial side face thereof, and second recesses in radial direction, the two semicircle slot holes being symmetric along the center of the rod-shaped rotor, and the semicircle slot holes on different axial side faces being axially aligned, and each second recess surrounding a semicircle slot hole; a first shaft mounted in the first through hole; a contact spring mounted in each first recess, the contact spring being able to move within a range defined by the first recess; a first connection member mounted on the rod-shaped block rotor, the first connection member being mounted within the two semicircle slot holes which are axially aligned, the first connection member being configured to slide within the second recesses using the semicircle slot hole as a rotation center, and the angle of rotation of the first connection member being limited by the length of the second recess, the first connection member having a second through hole, a convex short shaft on both sides of the first connection member and a plane thickness, the short shaft matching with the semicircle slot hole, the second through hole matching with a second shaft, and the plane thickness being not larger than a depth of the second recess so that the second recess can effectively limit a movement range of the first connection recess; the second shaft going through the first connection member for suspending the contact spring; a third shaft; a second connection member having a third through hole and a fourth through hole on both ends of the second connection member, the third through hole matching with the second shaft and the fourth through hole matching with the third shaft; the second shaft and the third shaft going through the second connection member respectively; and a contact bridge crossing through the rod-shaped block rotor, the outer profile of the contact bridge being centrally symmetric, the first shaft and the third shaft going through the contact bridge respectively, and contacts being welded to end points on both sides of the contact bridge. a single-phase independent rod-shaped block rotor having a first through hole at the center thereof, a first recess and two semicircle slot holes on each axial side face thereof, and second recesses in radial direction, the two semicircle slot holes being symmetric along the center of the rod-shaped rotor, and the semicircle slot holes on different axial side faces being axially aligned, and each second recess surrounding a semicircle slot hole;
