Straight forward and easy
Received a switch for a grinder. Customer service was friendly and took the time to find the part. It was an older grinder so it took a few weeks to come in, but I was informed of this upfront. Very pleases with eReplacement Parts.

Switched Failed on Milwaukee 5192 Die Grinder

Tools Used
Screwdriver, Crimpers, T20 torx driver
Parts Used
To replace the switch on these units is fairly easy to do as long as you are comfortable crimping wires. The screws themselves can either take a flat blade screwdriver or a T20 torx driver (preferable). You will need two (2x) closed end splices. You can get these from Home Depot SKU #298233 (pack of 10x).
1- Remove the three (3x) screws near the power cable on the backside of the unit. This will allow access to the switch and brushes.
2- Slide the old switch out of the housing and cut the two wire crimps that are attached to the switch leads.
3- Crimp the new switch wires back into place where the old switch was connected. This is a SPST switch so it doesn't matter which wire goes where, just get them both attached.
4- Slide the new switch back into the housing. The switch has a cutout that aligns with the tab in the grinder's housing to ensure proper orientation. Ensure the wires are pressed back into the housing so they won't be pinched by the back cover or the motor. The switch is actually held in place by the back cover so it will still be loose until that is replaced.
5- Replace the back cover and reinsert the three (3x) screws removed in step 1.
6- At this time you can plug the die grinder into the wall to ensure properly switch function.
Happy Grinding!
