Milwaukee Switch Kit
Model Number: 14-46-9320
The Milwaukee 14-46-9320 Switch Kit is a genuine OEM replacement part designed for the Milwaukee 2625-20 M18 Hackzall One-Handed Reciprocating Saw (serial code C41A), the original M18 Hackzall platform. This part replaces obsolete part number 23-66-2977, so if you have ordered the 23-66-2977 in the past, the 14-46-9320 is the current Milwaukee-issued replacement and is the correct part to order going forward. The switch kit is the integrated trigger switch and printed circuit board assembly (PCBA) that controls power delivery to the Hackzall's motor. The switch handles the trigger input from the operator, and the integrated PCBA manages the electronic communication between the switch, the battery, and the motor circuit, controlling the on-off function and the variable speed response that makes one-handed reciprocating cuts possible across a wide range of materials including wood, metal, drywall, plastic, and nail-embedded lumber.
Common symptoms of switch kit failure on the 2625-20 include the tool failing to start when the trigger is pressed, intermittent operation where the tool starts and stops randomly under trigger pressure, the tool running at a single speed without trigger modulation, the tool failing to recognize the inserted battery, or the tool continuing to run after the trigger is released. Because the original 23-66-2977 integrated both the mechanical switch and the electronic PCBA into one part, swapping the complete switch kit restores both the trigger function and the electronic control circuit in a single repair step, eliminating the need to diagnose whether the failure is in the switch contacts or in the control electronics. Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee 2625-20 service parts diagram (bulletin 54-40-2612) before ordering, since Milwaukee occasionally implements running production changes that affect part compatibility within the same catalog number. The 14-46-9320 is specific to the 2625-20 M18 Hackzall and is NOT interchangeable with switches from the M18 FUEL Hackzall (2719-20) or other M18 reciprocating saw platforms. Verify by serial number using Milwaukee's online parts lookup before ordering to confirm correct fitment.
