The invention discloses a magnetic attraction type pressure reduction mechanical forced starting device. The device is provided with a magnetic type transmission mechanism, a travel contact mechanismand a contactor group, wherein the magnetic type transmission mechanism is connected with a rotary handle towards the outside of the shell; the rotary handle controls the magnetic type transmission mechanism to be in contact connection with a contact of the travel contact mechanism and generates a switching value signal; the travel contact mechanism is electrically connected with the contactor group; the contactor group comprises a main loop contactor, a triangular connecting contactor and a star-shaped connecting contactor; the switching value signal enables the contacts of the main loop contactor and the star connection contactor to form star connection when the motor is started when being closed, and the switching value signal enables the contacts of the main loop contactor and the triangular connection contact
