The utility model discloses a reversing starter, which mainly comprises a lever, two coils, two static iron cores matched with the coils, a movable iron core, a transmission rod, a contact head bracket, an output terminal, an input terminal and a moving contact head. The movable iron core is arranged at the upper end of the transmission rod; one static iron core is arranged in each coil, and the static iron core is arranged on one end of the lever; the moving contact head is arranged on the contact head bracket; the contact head bracket, the output terminal and the input terminal are arranged on the other end of the lever; the output terminal and the input terminal are respectively arranged on both sides of the moving contact head. After adopting the structure when using, the two coils are not energized, so the contact heads are in the broken state. When the upper coil is energized, the utility model runs in the forward direction. When the lower coil is energized, the utility model runs in the reverse direction. Compared with the prior art, the reversing starter has the advantages of integrated and simple structure, no need for additional mechanical interlocking, small volume, convenient installation, safety, reliability, simple operation and lower price. The reversing starter can work when directly connecting with the power supply line.
