Craig, it's not impossible but it would be an unusual model that required a widget per channel, there is normally some doubling up e.g. 2 aileron channels per stick, one retract switch to run the legs and doors channels and so on.
Logic switches are software, not actual physical switches, which is why you don't see any more switches on the face of the 24 compared to the 16. Logic switches are of the sort that you say if A is on AND B is on then do something, else don't. For example my brake chute switch only works if the arming switch is on AND the throttle is at idle AND the gear is down. I also use a logic switch that checks if the throttle is at more than idle AND the wheelbrakes are on then speak "wheelbrakes are on" and keep repeating it so that I don't land with the brakes accidentally on and the wheels locked.
You have more controls that are invisible, the DS (but not the DC) has gyros in it which sense tilting or rotation of the Tx and these can be used where appropriate, for example on my glider I use tilt left to speak the elapsed time, some people use tilt back to operate wheel brakes, and so on. I have seen a video of a model being flown purely by tilting the Tx but I wouldn't recommend it!
