Electronic switch module with oppositely-arranged power switches and discrete heat sinks

A power tool comprising:

• a housing;
• an electric motor disposed within the housing;
• a battery receptacle formed in the housing that receives a removeable battery pack therein;
• and
• an electronic module mounted within the housing, comprising:
• a circuit board having a first surface and a second surface;
• a first conductive track located on the first surface of the circuit board and extending along a first axis;
• a plurality of second conductive tracks located on the first surface of the circuit board along a second axis parallel to the first axis;
• a plurality of third conductive tracks located on the first surface of the circuit board along a third axis parallel to the second axis;
• at least one first heat sink mounted on the first conductive track;
• a plurality of second heat sinks mounted respectively on the plurality of second conductive tracks;
• a plurality of motor terminals formed through the plurality of third conductive tracks;
• and
• a plurality of power switches mounted on the second surface of the circuit board configured as an inverter circuit to supply power from the battery pack to the electric motor, wherein the plurality of power switches comprises:
• a plurality of high-side power switches located opposite the at least one first heat sink and in thermal communication therewith, and a plurality of low-side power switches located opposite the plurality of second heat sinks and in respective thermal communication therewith.
