As far as I can tell, a single lever paddle, when connected to a
keyer, sends dots when pushed in on one direction and dashes when
pushed in the opposite direction. Presumably this prevents the
possibility of a keyer sensing both contacts closed at the same time.
Using a single lever paddle with a keyer that is iambic A, iambic B or
non-iambic is exactly the same.
It makes automatic dots and dashes, and is self-completing (which means
that once you start a dot or dash, the element and its following space
will be created regardless of when you let go of the paddle).
The only time there is a difference is when you close both contacts
together, which you can't do with one lever!
