The Milwaukee 23-66-2190 is a genuine OEM power switch designed for industrial-grade power tools. Constructed from thermoplastic, metal, and wiring, this component controls power delivery to the motor, functioning as either an on/off switch or a variable-speed trigger. It is engineered to handle full motor inrush and running currents while preventing arc-tracking. The switch is typically installed within the motor housing and left brush holder to facilitate tool activation and deactivation.
