Product Description

?

This is a Trigger type switch that has a battery connector and 3 leads connected to a heat sink. This genuine Makita 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.

There are only two wires involved. One goes from the switch to the motor and the other goes from the switch to the circuit breaker. These wires connect to two terminals on the switch that are barely legibly labeled M1 and M2. No matter, make a sketch or take a photo of where these wires are soldered to the old switch. If the switch has n ever been replaced before then there is plenty of wire length, just cut the two wires free from the old switch terminals. Strip the wires and solder them to the new switch. Account for every strand of the wires, no shorts. It is critical that the wires\' polarity is maintained or the drill will be damaged. Be careful with reassembly to be certain that nothing will short when the case is closed. Well worth the effort.

I opened up the drill, unsoldered the wires from the old part, soldered in the new part and reassembled the drill. Replacement part worked perfectly.
