This is an genuine OEM sourced replacement part used on Milwaukee electric drills/drivers and sawzalls. Switch is a crucial part of the tool which handles on/off operations. Because switches use mechanical internals, they will tend to wear out over time, eventually requiring replacement. It has a plastic body and it is sold individually.
To replace this switch you would need a Screwdriver.
• First you want to remove screws used to secure two pieces of housing set
• Disconnect wires from the old switch and remove it from the housing
• Place the new switch in the housing and connect wires to it
• Reassemble the housing

Removed half of the switch handle, then removed the switch from the handle. I made a wiring diagram. I disconnected the wires from the old switch and connected the wires to the new switch. Installed the new switch to the handle half. Put the handle half back on. It's working again, Thanks.
