**Milwaukee parts change not only by model# but also by serial number. Milwaukee’s site lets youlook up your tool’s parts diagram. Enter Cat# and Select Service Parts. Also match Serial Number.Milwaukee Switch AssemblyModel Number: 23-66-2365The Milwaukee 23-66-2365 is a genuine OEM Switch Assembly for the Super Hawg 1680-20 and 1680-21 heavy-duty drills. The switch assembly is the reversing trigger switch unit that controls the drill: it turns the motor on and off and sets the direction of rotation, forward or reverse, for the Super Hawg’s high-torque drilling. The assembly has a plastic body with the lead wires attached, wired into the drill’s handle. Because the switch carries the drill’s full current and is actuated on every pull of the trigger and every direction change, it wears electrically and mechanically over the tool’s life, and a failing switch can make the drill cut out, run only in one direction, or not start at all. Replacing it with the genuine Milwaukee OEM switch assembly restores reliable on/off and direction control with the correct electrical rating and connections, where an off-spec switch may not match the drill’s wiring or handle the current.This switch assembly is listed for the Milwaukee Super Hawg 1680-20 and 1680-21 drills, serials 407A, 407B, 407C, 407D, and 407E, and it may appear on additional Milwaukee heavy-duty drills that share the same switch, so confirm the fit for your exact tool. It works with the separate on/off switch (23-66-2270) and the lead wire assembly (23-94-2270), which are commonly serviced together and are sold separately; if the switch is failing, check the lead wires and companion switch at the same time. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.FeaturesGenuine Milwaukee OEM switch assemblyFor the Super Hawg 1680-20 and 1680-21 heavy-duty drillsThe reversing trigger switch unit that runs the drillTurns the motor on and offSets the direction of rotation, forward or reversePlastic body with lead wires attachedSerials 407A through 407E; verify by serial numberWorks with the on/off switch (23-66-2270) and lead wire assembly (23-94-2270)Restores reliable on/off and direction controlReplace if the drill cuts out, runs one direction only, or will not startSold individuallySpecificationsManufacturer: Milwaukee ToolPart Number: 23-66-2365Official Description: Switch Assembly (reversing switch assembly)Component Type: Heavy-duty drill reversing switch assemblyPrimary Fitment: Milwaukee Super Hawg 1680-20 and 1680-21, SER 407A through 407EAlso Referenced On: May fit additional Milwaukee heavy-duty drills; verify using Milwaukee’s online parts lookupParts Diagram Position: Switch assembly on the 1680-20 service parts diagram; verify the figure on the diagramQuantity: Sold individually (1 switch assembly)Part Type: Genuine Milwaukee OEM Replacement PartIncludes(1) Switch Assembly (with lead wires)The on/off switch (23-66-2270) and the lead wire assembly (23-94-2270) are NOT included and are sold separately, though they are commonly serviced together.
