sometimes it's just the old grease inside the switch has hardened . turn the 
145 on it's back and see if you can get some cleaner to run into the switch 
around the ball . will have to drip it slowly and let it work it's way in 
then add a little more and put an ohm metre on the switch and work it back 
and forth a few times and see if the mechanism loosens up . make sure it is 
a non alcohol based cleaner if you are going to clean a power switch .

if that fails Mouser.com has a good selection of switches .

good luck

My local restoration guru is restoring a HQ-145X and needs two matching
switches.  The original switches have a short handle with a little ball on
the end but switches without the ball are fine as long as the two match
otherwise.  They can be SPST or DPDT but the bushing length must be 3/4"
minimum.

Any sources?

"Meanwhile, trying to finish up the HQ-145X and have run into intermittent
operation of the toggle switches on the AGC and the Noise Limiter.
Sometimes they make internal contact, sometimes when they are switched off
they stay on.  I think they are just worn out and I see no way of servicing
them without destroying them.  I have spent many hours going through junk
drawers, catalogs, and the internet and have yet to find a simple toggle
that will be a suitable substitute.  The problem on a workable match is the
bushing length.  I need a panel bushing ?? long, everything made today is ?
inch long.  SPST switch action, bushing diameter of ? inch, bushing length
of ??, toggle operated.  Any ideas of where to find a matching pair let me
know?"
