The utility model discloses a pullswitch preventing pull line from being broken. Based on the existing pull wire switch, the axial direction of the connecting hole (3) on the rotating arm (1) is made consistently with the going direction of the pull wire. So that when working, the pull wire (4) is only forced by the tensile force but not cutting off action between the pull wire (4) and the hole wall of the pull wire hole (3), thereby, lightening the wear of the pull wire (4) and improving the service life of the pull wire (4).
