Could someone please check my design

    This is my attempt at a rotary momentary 2-position switch. The idea is
    that when the switch is in either position, it shorts two pins on a
    motherboard to turn it on or off. This project requires a rotary switch,
    so I can't just use a momentary pushbutton.

    Here's my design (sorry about the confusing switches, they were the only
    ones I could find in LTSpice):

    Is this sound? My thought is that by using a 2-pole 2-position non-
    shorting switch (in place of the DPDT switches in the circuit), I could
    have it charge one capactitor while discharging another and flipping a
    relay over. The duration of the momentary connection will be dependant on
    the size of the caps I use.

    As you probably guessed, I am a novice, but your help will most certainly
    be appreciated.

    Thanks!
    Jeff
