The one thing I never heard was why was the repitching a major mod?
Are the pitch specs specific to that engine/prop combo in a specific
airframe? Does the repitching exceed the prop manufacturer's limits? (aka
bad idea) If not is there another airframe with that same engine/prop combo
that allows this new pitch? If so I don't see it as a major mod.

Charlie,
I obtained my Carling Technologies 15 amp rated switches from Waytek Wire. They
had the best pricing. See
http://order.waytekwire.com/productdetail/M37/44266
http://order.waytekwire.com/productdetail/M37/44251
http://order.waytekwire.com/productdetail/M37/44253
http://order.waytekwire.com/productdetail/M37/44259
On items such as my Piper style pitot tube (heated), I used a DPST switch, as the
pitot has two heating elements. In this fashion, each element has it's own
pair of contacts, and amperage through each set of contacts is halved (compared
to using a SPST switch)
