Milwaukee Switch PCBA
Model Number: 23-66-0301
The Milwaukee 23-66-0301 is a genuine OEM Switch PCBA for the 0940-20 M18 FUEL Compact Vacuum. The switch PCBA is the printed circuit board assembly that carries the vacuum's power switch and slide control buttons: it is what the operator presses to turn the vacuum on and off and set its mode, and it relays power from the battery to the motor based on that input. Because it is handled on every use and sits in a dusty environment, the switch and its board can wear, fail intermittently, or stop responding, at which point the vacuum may not power on, may not hold a setting, or may behave erratically. Replacing it with the genuine Milwaukee OEM switch PCBA restores reliable on-off and mode control and the correct connection into the vacuum's wiring, where an off-spec board may not fit the housing or connect correctly.
This switch PCBA is identified as the Switch PCBA, Figure 19, on the Milwaukee service parts list for the 0940-20 M18 FUEL Compact Vacuum, serial L51A, bulletin 54-05-0285. It works with the vacuum's slide buttons and housing, and Milwaukee's service note is to check the slide buttons and switch for proper function before reinstalling the battery. It connects into the vacuum's wiring and motor, which are separate items. 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.
