What evidence do you have that your switches are connected correctly? The only evidence I've heard says they aren't correct.
You should have two wires going from each switch to the digital input port on the RC. For this application you will want to have one of the wires connected to the "normally open" (NO) terminal of the switch, and the other wire to the common (COM) terminal. According to the table on page 10 of the Full-Size Robot Controller Reference Guide, switch 5's NO should be wired to pin 4 of the digital input port, and switch 6's to pin 5. The COM terminals of each switch must be connected to a ground pin (3, 6, 9, 12, 13, 14, 17, 20 or 23) on the input port.
