I have this Dremel tool (made by a Canadian Co.) about 15 years old and the VS switch is gone (works only at very low speed). I was thinking if there is way to bypass the VS switch and connect the power straight to the motor and then use a router speed control I have (shown on last picture) to control the speed.

The pictures shows the motor with the VS module plugged at the end. This module has 4 pins plugging into the motor and I have identified each pin for help. My problem is that I can see the B terminal (which the Black wire connects into) also connect to one end of the VS switch but I can’t see where the other end of the switch connects.

Is it possible to remove the VS switch?
