[Healeys] dash switches

[pdeturck at rochester.rr.com]

I have a couple of switches on myBJ8 dash (notably the
Panel Lights and Overdrive) which are starting to
fail. They seem to work most of the time but if the
actuator is moved side to side even a little bit the
internal connections seem to disconnect when
the switch is actuated.  The wire connections on the
back are tight and clean.

Can these switches be rebuilt in any way?
Are "new" switches similar in appearance and tactile feel?
Does anyone have any NOS available?
Thanks.
