Milwaukee Switch Lock Out Button
Model Number: 42-42-0345
The Milwaukee 42-42-0345 is a genuine OEM Switch Lock Out Button for use in compatible Milwaukee tools. The switch lock out button is the safety mechanism that must be depressed or engaged simultaneously with the trigger to allow the tool to start — preventing accidental motor activation if the trigger is bumped or inadvertently pressed without deliberate operator intent. Lock out buttons are standard safety features on Milwaukee angle grinders, rotary tools, and other high-speed tools where accidental startup would pose a serious safety risk. A broken or stuck lock out button that prevents the tool from starting, or that no longer requires intentional engagement before trigger actuation, requires replacement to restore correct safety interlock function.
Using a genuine Milwaukee OEM switch lock out button ensures the correct engagement geometry and actuation force for the safety interlock it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct button for your specific unit.
