After loosing 3 airplanes to suspected switch problems, I have standardized on the use of HD 2-pole switches. Most of my larger airplanes have MPI switches on them. They are more costly than OEM switches, $15.00 vs $8.00, but considering they are mounted on airplanes with investments of between $800.00 and $1700.00 they are worth the extra few dollars.
Do you have part numbers and where to buy them? Why two poles? Reduntant batteries?
