An overspeed protection switch, an overspeed governor assembly and an elevator system are provided. The overspeed protection switch includes: a trigger member, which is in an untriggered position when the overspeed governor assembly is in normal operation, and which is capable of rotating to a triggered position from the untriggered position when being toggled by a centrifugal mechanism of the overspeed governor assembly in case of overspeed of the overspeed governor assembly; at least one protrusion connected to the trigger member and rotating together with the trigger member; a reset lever which is rotatable along an axial axis from an idle position to act on one of the at least one protrusion to drive the trigger member to return to the untriggered position from the triggered position; and an actuation device which, in response to a reset command, acts on the reset lever to rotate the reset lever.
