Milwaukee Switch
Model Number: 42-42-0003
The Milwaukee 42-42-0003 is a genuine OEM Switch for the M18 Brushless Precision Blower. The switch is the control component the operator actuates to run the tool, carrying the input from the trigger through to the blower's electronic control so the motor responds correctly. The 0887-20 uses a variable-speed trigger with a lock-on feature and a three-mode power selector, and the switch component is central to that control: a worn, cracked, or intermittent switch shows up as a tool that will not start reliably, will not hold its speed, or will not lock on for extended cleanup. Replacing it with the genuine Milwaukee OEM part restores correct fit and consistent switch action, where an off-spec part may not seat properly in the housing or actuate the control cleanly.
This switch is a service part for the Milwaukee 0887-20 M18 Brushless Precision Blower. Confirm the exact figure position and Milwaukee's full description for this part against your tool's service parts diagram, since Milwaukee lists switch-related components by their precise position in the handle and control area. The switch works together with the tool's electronic control board and wiring, which are separate service items and are ordered separately as needed. 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. If you are not certain this is the correct switch for your unit, look up your catalog and serial number using Milwaukee's online parts lookup before purchasing.
