The invention discloses a control circuit for interlocking of elevator contactors. The control circuit comprises a first switch, a second switch, a third switch, a first fuse, a second fuse, a third fuse, a first resistor, a second resistor, a third resistor, a first button switch, a second button switch, a third button switch, a motor, a normally-closed contact switch of a first contactor, a normally-closed contact switch of a second contactor, a normally-open contact switch of the first contactor, a normally-open contact switch of the second contactor, a first switch of the first contactor, a second switch of the first contactor, a third switch of the first contactor, a first switch of the second contactor, a second switch of the second contactor, a third switch of the second contactor and a thermal relay. The first contactor is electrified and closed, and the motor rotates forwards; the first contactor is locked; firstly the motor stops running; then the second contactor is electrified and closed, and the motor rotates reversely; the second contactor is locked. According to the invention, when the motor rotates forwards, the first contactor is locked; when the motor rotates reversely, the second contactor is locked, and therefore the control circuit can work stably.
