I was wondering if someone could sanity check this schematic and tell me if I am doing something wrong?  What I have is one 3 position momentary toggle switch (common + two poles, normally off in center) and two reed switches all configured with pull down resistors to the Digital IO pin.  (These are simulated in the diagram below with momentary pushbuttons.)  If I define all four inputs (D8, D11, D12, D13) as InterruptPorts and assign NativeEventHandlers what I am seeing is that if I push any one of the buttons then most or all of the other handlers get fired?  The other handlers report that they are False on both edges, but they are still being triggered.

Does this make sense?  I am thinking this has something to do with them sharing 3.3v, but not sure?

Any thoughts are welcome.  Thanks.
