I really prefer the flat slide switches that mount on the outside of the aircraft. I set them up so that pushing them towards the rear of the aircraft turns the power on. Being flat, they can't be turned on or off by bumping or brushing the fuselage. I also use Voltwatch and put it in a visible location so that a quick glance, lit LED's mean the power is on.

Exactly as I do.
Whatever you do, make sure that the switch is relatively protected. At our field, I saw a mid-air in which one of the two planes seemed barely damaged in the collision, but then proceeded to dive into the ground with a concurrent loss of control. When the parts were recovered, the power switch was in the OFF position. It was switched off during the impact.
