1. Removed screws from saw handle and removed the cover.
2. Removed old switch from the handle.
3. Disconnected the wires from the old switch and attached each to the new switch (disconnecting and attaching the wires one at a time to insure their proper placement on the new switch).
4. Put the new switch back into the handle
5. Replaced cover on the handle and reattached the screws.

The whole story: Makita circular saw. Initially, it would take several presses of the trigger to get it going. Over time it took more "trigger presses" and eventually it simply died. I took it apart in search of something obvious but found nothing. Upon reassembly, as soon as I plugged it in it would run (almost lost a finger or two) continuously until I unplugged it. I bought a new switch, replaced it, and it now functions like new. ereplacementParts is an awesome website as it guided me to the correct part quickly at a fair price.
I removed the handle cover and the cord clamp. Made a wiring diagram of the switch wires, then removed the wires. Connected the wires to the new switch, tightened down the cord clamp and installed the handle cover. Thank again!

Pretty simple, I think it took longer to find the part on the web. Flat head screw drive or a phillips Take the screws out of handle around trigger. No need to take any other scews out until you pry the handle apart, it is slotted has come straight out, then unscrew the cord, pop the old trigger out Remove screws in electrical connections . then put it back together.
