Milwaukee Marquardt Switch - 1269.R164
Model Number: 23-66-1813
The Milwaukee 23-66-1813 is a genuine OEM Marquardt Switch, Marquardt model 1269.R164, for the 6470-21 10-1/4 in. Circular Saw. Marquardt is a manufacturer of high-quality trigger switches used in professional-grade power tools, and this switch is the Marquardt-manufactured trigger assembly used in this saw, providing the on-off motor control that responds to the operator pulling and releasing the trigger. The switch carries the full motor current every time the tool is run, so it is a genuine wear and electrical component: over time and switching cycles a trigger switch can wear out or fail. A sign that the switch is wearing out is trouble starting the tool, or the tool working only once it is already running, or intermittent off-and-on operation. A switch that causes intermittent power, sticking trigger action, or a complete failure to start or stop the saw requires replacement to restore reliable motor control. Using a genuine Milwaukee OEM Marquardt switch ensures the correct current rating, trigger travel, and wiring interface for the saw, which an aftermarket switch cannot be counted on to match.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before placing your order, since running production changes can alter part compatibility within the same catalog number. This switch is specified for the 6470-21 10-1/4 in. Circular Saw, including serial B49A, so confirm your tool's catalog and serial number against the parts diagram before ordering. Because this is an electrical part, replacing it involves disconnecting the tool from power and working with the internal wiring, so note or photograph the wire connections before removing the old switch, and route and connect the wires exactly as original on the new switch. Service should be performed by someone competent to work on power tool electrics, following the tool's service procedure. The wiring, cord, and related electrical components are separate parts, so refer to your tool's parts diagram for the correct companion part numbers.
