If , like me, you never use the speed control on the Jigsaw, you can remove it permanently, and bypass it.

To do so, you will need to cut the wires between the switch and the PCB, and the PCB and the motor.

Then join the white wires together, and the black and blue wires together. The multi-pin connector is for the variable speed trigger and is not required.

I did this by soldering them together and covering the joints in Heat-shrink tubing.

It is recommended to add an X2 0.1μF 310V capacitor between the white and black wires to prevent electrical noise and excessive sparking from the motor brushes, which would shorten the life of the motor, I did this by soldering one leg of the capacitor to the joint between the white cables and one to the joint between the blue and black wires.

Take care that the wires are routed correctly through the notches in the case frame, so they will not be compressed when you reassemble the saw
