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.

Spare parts for older machines are often either unavailable or surprisingly expensive (e.g. armature £37).
You'd need to open up the case and see if there is any other internal damage.
You might need to fabricate or improvise a speed selector. For example you might use polymorph or adapt a metal part.
A new Bosch drill of that sort can be purchased for £35-£50 (PSB500RE PSB680RE are often available on special offer at 30% lower price). A cheap store-brand drill might be £20 or less.
