This is a soft rubber protective cover for the on/off switch on your tool. This authentic Makita replacement part is sold individually. Switches are commonly replaced parts in power tools, handling all 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: • The tool has stopped functioning - it refuses to 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.
