This is a Push-Button type switch that has 4 terminals, 2 internal and 2 external. This genuine Makita replacement part is sold individually.
rnrnSwitches 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:
• The tool has completely stopped functioning – it will not start.
• The tool operates intermittently, requiring multiple tries to turn on, until eventually it won’t start at all.
• The variable speed function and electric braking aren’t working properly.

This video clearly shows all the steps and made me confident that if I ordered the part, the fix would be pretty easy. It was exactly the same model of Makita grinder and well explained. I had a little bit of trouble fitting the two halves if the black plastic housing back - there are some channels that the wires need to be pushed into to make them fit snugly and not get in the way of joining the two parts back together. But that that just took a little care and patience. The grinder works like new now.
