This is a Genuine OEM Milwaukee Replacement Push Button Switch used for Angle Grinders. It includes the screws used to attach the Lead Wires. Switches are commonly replaced part in power tools. A switch handles all on/off and variable speed functions. They also have a role in electric breaking because they can momentarily reverse electrical polarity. Since switches use mechanical internals, they tend to wear out over time and will eventually require replacement. A screw driver is needed to take the casing off of the tool to access the switch.

I assumed it was either the switch or the PCB, so I replaced both and it now works. My suggestion is take pictures and note where the wires route. The new switch did not come with some special clips but was able to reuse clips from the old switch. The only real difficult part is the reassembly... getting the wires and PCB stuffed back in position definitely takes patience.
I say "Thanks" to the people at eReplacementParts.com for keeping my order open until the manufacturer (Milwaukee) was finally able to supply the needed parts.
Grinder would not power up when switch level depressed.
