Aftermarket Push Button Switch replaces Makita 651947-7 and Bosch 1607200146.
Switches are commonly replaced parts in power tools. A switch handles all on/off and variable speed functions. They also have a role in electric breaking; they can momentarily reverse electrical polarity. Because switches use mechanical internals, they tend to degrade and wear out over time, eventually requiring replacement.
This Push-Button switch has 4 terminals and a compact design for easy installation. This authentic Makita replacement part is sold individually and replaces Makita part number 651947-7 and Bosch P/N 1607200146.
NOTE: Some common signs of a broken or failing switch are:
The tool will not start when you use the switch, or it requires multiple tries to turn on, until eventually it refuses to start at all
The variable speed function and electric braking aren't working properly
