This Push-Button type switch has 3/4 terminals. This genuine Makita replacement part is sold individually.
Switches are commonly replaced parts in tools. A switch handles on/off and variable speed operations. They also have a role in electric breaking; they can momentarily reverse electrical polarity. Because switches use mechanical internals, they will degrade and wear out over time, eventually needing replacement. Some common signs of a broken or failing switch are as follows:

It was the correct part!
Perfect fit. I had ordered a "guaranteed replacement" part from another seller. It turned out to be a generic part that needed drilling and had too many contacts. It also came with no wiring diagram. The switch I received from E-replacement was a the correct one with the proper wiring terminals. So easy to replace and exactly like the original. Thanks!

Fixing blade guard was more interesting than another switch, used screwdriver to work out spring washer and replace with new part.hardest thing is making sure the spring doesn’t off into the yard..
