    A couple of questions:

    What configuration of toggle switch (SPST, SPDT, etc) would I need to do the following:

    Down position - Off - Input not connected to any output

    Center position - Low - Input connected to one output

    Up position - High - Input connected to second output

    This would be used to feed a strobe power supply that offers both a low and a high output. A source of supply for this switch would also be appreciated.

    Second question:

    The Rotax 503 wiring diagram calls for a 15-amp fuse between the rectifier-regulator and the positive battery terminal. Would there be any reason not to use a combination toggle switch/circuit breaker, such as the W31X2M1G-15 from Wicks Aircraft Supply for this purpose?

    Thank you!

    It would be much easier, and perfectly acceptable, to do it this way:

    UP = HIGH
    MIDDLE = OFF
    DOWN = LOW

    A simpl SPDT with a center position OFF would work. These are available at Chief Aircraft, Wicks, Aircraft Spruce, Digikey, Jameco, to name a few.

    Stupid, I know, but since all of the other switches will be "down" when "off", I would like to keep things consistent...

    Hey, NO PROBLEM.

    Try Mouser Electronics:

    www.mouser.com

    Search for "ON-ON-ON Toggle Switch"

    This should turn up a few candidates. I looked at one in particular that should work in your application:

    54-362 - Spade Terminal
    54-371 - Screw terminal

    Good Luck
