Undisturbed switching control circuit and motor start-stop control system

The utility model relates to the technical field of motor start-stop control, in particular to an undisturbed switching control circuit and a motor start-stop control system. The circuit comprises a local control branch, a remote control branch, a first change-over switch, a first time relay, a second time relay, a first intermediate relay and a second intermediate relay. Time relay, when the remote control mode is switched to the local control mode, the operation is simple; firstly, a local control branch is switched on; then the remote control branch is disconnected; when the local control mode is switched to the remote control mode; according to the utility model, the remote control branch circuit is switched on firstly and then the local control branch circuit is switched off, so thatthe motor equipment cannot be powered off in the control mode switching process, undisturbed switching from remote control to local control is realized, normal operation of the motor equipment is maintained, production interr
