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