OK well lets assume that you mounted the 2 SPST switches so that in the down position
the switch is in the 'open' position and when you flip it up it is in the closed
position.Switch 1 is connected to pins 11 & 12 of the chip and switch 2 is connected to
pin 10 and ground.
switch 1 DOWN switch 1 UP switch 1 UP
switch 2 UP switch 2 UP switch 2 DOWN
