Difficulty

Time

Tools Used
Screwdriver, Power Drill, Soldering iron
Remove all screws to open up drill - about eight
I recommend taking several detailed pictures with your smart phone paying special attention to which wires attach to which terminals of the switch
Very carefully remove the internal parts keeping them together as one unit and make note that the motor has a keyed slot that will need to be aligned into the new handle
Melt the solder off of the old broken switch 4 wires total
Solder wires onto the new switch in the same way they were removed - if you get this wrong the drill may operate backwards
Clean up the parts and pieces removing any old build up and check the brushes - they may need to be replaced - grease rotating elements - I used white lithium grease
I recommend leaving the brushes out until reassembly is almost done
Install the parts in to the new handle - pay attention to the keyed slot in the motor and align it to the handle first
Snap in the remaking parts
Screw the two halves of the handles back together paying attention that all of the wires are in the internal grooves of the handles and don't let them get pinched as you screw the halves together
Insert the brushes

I had to heat and remove 4 soldered wires from the old controller and re-solder the wires onto the new controller. Closing up the gun with all of its parts aligned was a bit challenging.
