I've thought about this and asked my Mom, who BTW is one helluva Electrical
Engineer, wether or not it could cause a problem. She pointed out that the
meter reads the speed setting in absolute values, i.e. 1/125, 1/8, etc..
When the dial is moved from one of these values to the adjacent value a
circuit is switched to the new value. This is done by rotating a contact
into physical proximity of a stationary contact. It is feasible that at some
point in the rotation the contacts for the previous speed and that for the
newly selected speed are BOTH in contact with the stationary contact.
Jamming it between speeds may prolong this and fry the little bastard. Not a
fact, just a possibility. My Mom, you gotta love her.
