On-Off Trigger Switch 3132421046

This Trigger type switch has 4 internal terminals. Included are 4 screws. This genuine Skil 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.
