Milwaukee Switch for Select Milwaukee Power Tools
Model Number: 23-66-0177
The Milwaukee 23-66-0177 is a genuine OEM Defond on/off switch for select Milwaukee corded power tools including the 5398 Hammer-Drill, 1001-1 Drill, and 6405 and 6407 Circular Saws. The switch is the four-terminal on/off trigger that controls power delivery and variable speed functions — the component the operator depresses to start the tool and releases to stop it. This switch replaces obsolete Milwaukee part numbers 23-66-0167 and 23-66-0505. Common signs that a switch requires replacement include the tool failing to start when the trigger is engaged, requiring multiple attempts to turn on, or loss of variable speed control. A worn or non-functioning switch requires replacement to restore reliable power control on the compatible tool.
Using a genuine Milwaukee OEM switch ensures the correct terminal configuration and current rating for your specific tool. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct switch for your specific unit.
