The utility model discloses an electrical isolation switch turn button shaft connection member. A distribution board of an electrical isolation switch and a plastic rotation button are connected through a 45 steel shaft connection member. A shaft cross section of a connection end of the shaft connection member is a regular quadrangle. By changing materials and a shape of an original shaft connection member, and by employing the regular quadrangle 45 steel shaft connection member, the electrical isolation switch turn button shaft connection member solves problems of easy damage and poor versatility existing in an original polygonal star-like plastic shaft connection member and further reduces use cost, moreover, the rotation button connected with the shaft connection member is a plastic product, so an insulation effect is realized, and personal safety of workers is guaranteed.
