Product Description

?

This Trigger switch has 4 internal terminals. This authentic Milwaukee replacement part is sold individually. rnrnSwitches are commonly replaced parts in power tools. A switch handles all on/off and variable speed functions. They also have a role in electric breaking; they can momentarily reverse electrical polarity. Because switches use mechanical internals, they tend to degrade and wear out over time, eventually requiring replacement. Some common signs of a broken or failing switch are:rn • The tool will not start when you use the switch, or it requires multiple tries to turn on, until eventually it refuses to start at all.rn • The variable speed function and electric braking aren't working properly.

Took off the handle around the switch and removed bad switch. Connected new wires, put new switch back in place and replaced handle. This would have been a lot simpler if the new switch had some instructions included explaining that the replacement switch did not wire exactly like the old one. I went back to ereplacementparts website to s ee that other folks had the same problem. After that it was much easier.

The terminals on the replacement switch were a different configuration than those of the original. A quick multimeter test confirmed the correct configuration. One wire needed to be extended and new terminal ends installed. Otherwise a direct fit in my Milwaukee circular saw.

This switch is slightly different than the original. The input & output terminals are in a different arrangement. That made this harder than it should be.

Searched online for instructions, found service bulletin 58-01-0753 from Milwaukee Tool describing installation. It can be obtained directly from Milwaukee Tool:

Took apart the case
Be careful not to mix up wire connections obviously
There was an extra wire that went to the directional switch,so i just hooked it to a hot wire
I used round terminals to finish the connections because those screws were tiny.
Overall it was an easy repair.
MAKE CERTAIN you put the screws in and snug them as soon as you open the package .
it is a contact switch and there are small copper part that are loose inside the switch they fell out when I took the switch apart.
Turns out you don\'t have to take the switch apart but that is how the old switch went together
hope that helps someone
