[Elecraft] OT: foot switch - why?

[DOUGLAS ZWIEBEL]

I have a Line Master 632-S which is decades old.  I used when I used
to do M/M contesting (multi-op, multi-transmitter).  You could
probably drive a tank over it without damaging it.

When lots of op's all talk at once and they are in close proximity to
each other, you can't use vox.

Which begs the question...why do folks use a foot switch from home if
they are the only one in the room?  I use vox.
