switches will fail more often because it th one item in the power system where the builder spends the least amount of brain power. I have never, other than on my own planes seen a switch mounted  with silicone rtv between it and the fuselage. These little items are seldom vibration isolated. yet, the batteries, fuel tank, reciever, servo's everything inside the aircraft is vibration isolated...........not the swtich.

isolating the switch goes a long way to preventing its failure. HAving two of them I now believe is a good idea with a smaller battery connected to each.

Forge to switch one on? Well maybe once, but twice in a day? then perhaps the user needs to retake their solo test because airplane operations and checklist are part of the test.
