Switches 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:
