Many years ago, the resident engineer at Lafayette Radio's 100 6th Ave. NYC store, Bob Murray, taught me about rotary switches. Break before make is non-shorting. Make before break is shorting. The cumulative connection of contacts is sequence shorting.

Mr. Murray used his hands to illustrate what goes on. The index finger of 1 hand bouncing from finger tip to finger tip, for non-shorting. The index finger sliding from a tip into the gap between 2 tips and on to the 2nd tip, for shorting. The curved finger advancing along the tips, never loosing contact with a tip once connected, for sequence shorting.
