Product Details: This Trigger switch has 2 terminals and 3 leads attached to a heat sink. It also has a forward/reverse lever on the switch. 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 requiring replacement. 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. What is included: 1PC.
