Switch 650579-7

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.
