[Boatanchors] Truck radio part needed

[Rob Atkinson]

I have two large switches.  I got them at a hamfest last year.  They
were in a box with a bunch of other switches and I bought them because
they were interesting, but I will probably never use them.  One looks
like it is a big DC switch for an automobile radio or something.  they
are not exactly "push button" but more like a pull click shaft with a
chrome knob.   You pull them out until they click, and push them in
(to break contact I suppose).

Actually one has three switch contacts, two labeled Bat and Head; the
other is SPST.

The SPST has a threaded panel mounting shaft with two nuts on it and
is 7/16 inch diameter.  The length of the switch including the knob
and rear terminals is 4 inches.  The height of the switch box is 1 1/2
inches.  Width is the same as the threaded shaft diameter but the knob
flares out so it can be grabbed and pulled.

The one with three contacts it turns out has a click stop halfway out
in addition to all the way out.  Its length is 3.75 inches (lengths
are with the knob all the way in).  The three lug connections are on
the side of the switch box.  Maximum width including the lugs is 1 3/8
inches.  Height is 1.5 inches.  The threaded shaft diameter is 3/8
inch.  This is a SPDT switch with one lug made to common with the
shaft halfway out and both lugs made to common with it all the way
out.  I imagine "head" means headlights and it was an old dashboard
light switch.  you probably want the spst for the radio if you want
any of these.
