What are you trying to prove by having three oil temperature senders? Why
the complexity? Best option is really in a location where oil flows or in
the pan. If using an adapter in between or in place of the oil filter a
sensor in the adapter on the outside (where the oil leaves the case) will
really give a good indication of how well the cooler is working.

Subject: How to find a particular three-way electrical switch.

Hello vanagon crew,

I'm in the process of wiring up three VDO oil temperature senders to
one gauge (one on my pan, and one in each to/from line to my oil
cooler) and for the life of me am having a tough time finding a good
switch to select from the three inputs. I went all over town today
(Radio Shack, West Marine, some local places) to find something and
everyone has on-off-on SPDT switches or DPDT switches but nothing that
is three-way. I don't care if it's a rocker, rotary or toggle switch,
just that it'll mount on my dash somewhere!!!

Any suggestions of what and where to buy this are MUCH appreciated.

Thanks,
Luke
