In my experience, in the UK, 'shorting' means 'progressively shorting', and is
used for shorting out bits of tank coil. It can also be used for receiver type
circuits, where unused coils are shorted out, usually by means of a ring on the
rear of the switch. 'Shorting' and 'non shorting' in US terms are defined when
you design the switch onto the switch manufacturers templates - it depends on
the width of the tongue which it is. 'Oak' switches which came from a company
called NSF and from AB Metals allowed the choice. AB seem to have dropped out,
but NSF is still going well, and they still do ceramic switches.
