Milwaukee Trigger Switch
Model Number: 23-66-2685
The Milwaukee 23-66-2685 is a genuine OEM Trigger Switch for Milwaukee angle grinders. It is the trigger control fitted in the rear handle assembly of the grinder, the switch the operator squeezes to power the tool on and releases to shut it off. It carries the full motor current every time the grinder is run, and it is the operator's primary on-off control, so reliable switch operation is essential to using the tool. Because the switch is actuated on every use and combines mechanical contacts, wiring, and a plastic body, it is a genuine wear and electrical component: over time and switching cycles a trigger switch wears out. Signs that the switch is failing include the tool being hard to start, working only intermittently, cutting in and out, or not starting or stopping reliably. A switch that causes intermittent power, a sticking trigger, or a complete failure to start or stop the grinder requires replacement to restore reliable, safe control. Using a genuine Milwaukee OEM trigger switch ensures the correct current rating, trigger travel, and wiring interface for the grinder.
This trigger switch replaces the obsolete part number 23-66-1812, so it is the current replacement if your tool originally specified that number. Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, and because this trigger switch is a common part used across a wide range of Milwaukee angle grinders, always verify your tool's serial number against the official Milwaukee service parts diagram before ordering to confirm this is the correct switch for your grinder. It fits many grinder models, including the 6123-31 5 in. and 6 in. rat tail angle grinder and related trigger-handle grinders, 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 power and working with the internal wiring, and a hex key and pliers are typically needed for installation, so note or photograph the wire connections before removing the old switch and route and connect the new switch exactly as original. Service should be performed by someone competent to work on power tool electrics.
