The invention discloses a mutual control reversing action circuit of a dual three-phase alternating current railway signal switch machine. The circuit comprises a first switch machine and a second switch machine which are used as three-phase alternating current switch machines; the first switch machine comprises a first switch machine alternating current motor and a first switch machine self contact group which are in conductive connection; the second switch machine comprises a second switch machine alternating current motor and a second switch machine self contact group which are in conductive connection; the first switch machine alternating current motor and the second switch machine alternating current motor are respectively and conductively connected with an external alternating current power supply. The external alternating current power supply is conductively connected with the first switch machine self contact group and the second switch machine self contact group through the control switch; and the first switch machine self contact group is conductively connected with the second switch machine self contact group through a wire. According to the invention, on-off control is carried out on the contact groups of the two alternating current switch machines, so that the running-in test and service life test requirements of the switch machines can be met.
