Luke,
A rotary switch would take the least amount of concentration to operate
while you are driving. They are easier to install than a slider( round hole
vs. square).

Subject: [VANAGON] 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.
