I have tried a couple of different things for switches...

On one plane I wired up a normal connection socket so that I could
plug in either a ESV to 1 and 2 or a special 'turn on the Rx' jumper
plug to 2 and 3.  Had the side benefit of having the charger connection
built-in and ready for use on the outside.

On another plane (still in progress) I have placed a standard switch
inside aligned side to side.  In line with the switch I have glued inner
nyrod guides and aligned small holes in the fuselage sides.  The switch
is actuated by sliding a special rod into either side of the fuselage:
one side to turn on and one side to turn off.  Advantages include no
large holes and nothing sticking out.  Disadvantage is you can't tell
at a glance if the Rx is turned on or not and it requires a "special"
tool for operation.

A word of warning to 'gas' plane owners however:  do not use anything
but a *positive* connection for the switch.  Normal toggle switches,
phono jacks, etc. with spring loaded contacts are not suitable for use
where engine vibration exists.

And a suggestion... when selecting or customizing switch setups look
for double pole switches and then connect both poles in parallel.  This
provides some degree of fault tolerance via redundant connections.  Most
all of the standard Rx switches are of this type and setup this way (as
well as many Tx switches).
