Superior Electric L50 Aftermarket Trigger Switch 24/12A-125/250V replaces Makita 651172-0, 651121-7 and 651168-1

Superior Electric L50 Aftermarket Trigger Switch replaces Makita 651172-0. This switch can be found in many Makita circular saws and grinders. Switches are commonly replaced parts in power tools. A switch handles all 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 tend to degrade and wear out over time, eventually requiring replacement. This switch proves to be a worthy replacement with supreme quality and a lower price to go with. NOTE: Some common signs of a broken or failing switch are: Tool has completely stopped functioning - it will not turn on Tool operates intermittently, requiring miltiple tries to turn on, until eventually it won't turn on at all Variable speed function and electric braking aren't working properly This part is compatible with: Makita: 5007S Circular Saw, 5007NB Circular Saw, 5008NB Circular Saw, 5007FK Circular Saw, 5007NBK Type 1 7-1/4" 15A Heavy-Gauge Aluminium Base Circular Saw, GA6010Z 10.5A 6" Cutoff / Angle Grinder, GA5010Z 10.5A 5" Angle Grinder, 5057KB 7-1/4" Circular Saw, 5007F 7-1/4" Circular Saw with Brake, GA5010, GA6010.
