Ted,
If you cannot find the SPDT relay, you can always spring for a DPDT. If
nothing else you have a redundant set of contacts or you can double up for a
bit more current carrying capacity
A good source is Digi Key
Here is the link for some good choices. The LY2F-DC12 by OMRON would not be
a bad choice at about seven and a half bucks.
