Agreed, but mount the switches on RF rated
plastic plate. I've seen these switches fail when
mounted to metal panels or brackets at only 2.5kv.
The indexing is so heavy-duty that you should
disable the rear one when ganging two of them for
Pi-L switching. They are highly regarded amongst
the ZL homebrewers.

<6-POSITION CERAMIC TAP SWITCH for 100
W BC-375 xmitter;
2.3x2.3x1.8, 1 lb. NEW #3Z9605 $3.95 ea 10 for
$32.00
These switches will stand a lot of volts and amps.
They have 30
degree indexing, and a fairly heavy duty indexing
mechanism.
There was an article in CQ 12 or more years ago
on ganging two of
them. You'd have to try them at 4kV, but I feel they
would
manage. You might be able to use the parts to
build something
with more volts if needed. The price is not likely to
break the
piggy bank, either.
