ABSTRACT:
The present invention relates to a control circuit for motor of electric jogging device in which a safety switch is disposed between an electronic loop and a power switch and which has an inserted safety plug-in pin to connect the power in an ON state. Accordingly, when the safety plug-in is removed from the fastening position, the second safety switch will be shut down in an OFF state so that the power won't enter into the electronic loop again and the motor won't be driven, and the safety of the user can be ensured.
