This genuine Bosch replacement part is sold individually. Switches are commonly replaced parts in power tools. A switch handles 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 will degrade and wear out over time, eventually requiring replacement. Some common signs of a broken or failing switch are: The tool has completely stopped functioning – it will not turn on. The tool operates intermittently, requiring multiple tries to turn on, until eventually it won’t turn on at all. The variable speed function and electric braking aren’t working properly.
