I have a Bosch CSB 500-2 2 speed hammer drill for wood, concrete, and steel. As can be seen in the image below, the speed selection knob is missing.
Would it be simply buying a new selector, which I imagine is pretty simple and inexpensive, and just opening the machine and slotting it in, or is this repair more complex than I envision? If more complex, I would appreciate a short summary of what needs to be done, but I am not looking for instructions on how to do it.
