Helmut you saved me again, thank you. Part of the confusion that I had
was that I don't really know what the syntax should be. What I did was
cut and pasted the example in the help file to my library and renamed
it. What I didn't realize was that the command didn't include
everything below the 'Example:'. After looking at your example the
help file made more sense. This got me thinking.
What would be helpful would be actual working examples (similar to
what you did for me) using the circuit elements and commands in a
single file. Also what would be useful would be an explanation of the
error codes (I figured out that multiple instances of W1 was a result
of having more than one library, I tried placing one in different
places to get one to open, with the same switch model in each). Maybe
the powers that be at Linear Technology can throw something together
and put it in the Files location on this site. Or if any of the
members have a little tidbit that they found useful maybe we can set
up a folder for them? Anyone have thoughts on this one?

OK where did I go wrong, I'm getting - Could not open include file
"MYLIBRARY1.LIB"
I copied the switch out of help, and the library is in the sub
directory.
MYLIBRARY1.lib
*SYM=CSW
.MODEL CSWITCH1 1 2
W1 out 0 Vsense CSWITCH1
Vsense a b 0.
.model CSWITCH1 CSW(Ron=.1 Roff=1Meg Vt=0 Vh=-.5)

Hello Bunny,
the problem is that your model/subcircuit doesn't follow SPICE
syntax.
Your switch model in the library has to be only:
.model CSWITCH1 CSW( Ron=0.1 Roff=1MEG It=1 Ih=0.5)
Only lines like these can model CSW switches. See the help pages.
All the other things have to be done in the schematic.
I have never used a CSW before and frankly speaking I tried in
the schematic until the netlist followed the syntax in the help
pages.
Finally I was successful. The value of the CSW symbol must contain
two values either in value-line or in the second field value2.
Right click over the symbol to look at.
value: V1 CSWITCH1
or
value: V1
value2: CSWITCH1
Best Regards
Helmut
