[Amps] Band switch types

[garyschafer@attbi.com (Gary Schafer)]

What is the difference if the band switch is a progressive shorting type
or just tap's the tank coil? Is there any difference in coil Q or
losses?
I know that the voltage can be quite high on say the 40 meter tap when
the switch is set on 20 or 15. With a switch with enough contact spacing
does it matter?

Thanks
