I think what should be used is a single pole, double throw switch. on-off-on

They do make an "Air Switch" that has two plugs on it that switches back and forth like a three way. Hit the switch, and the unit takes power supplied to a Hot water dispensor, and turns on the Disposal. Hit the switch again, same in reverse...

However, I wouldn't think of using it, or a 3-way switch like that for a Dish Washer. It would become a nusiance to the home owner to reset the DW cycle everytime the GB was used. And you would have the HO curse your name every time they remembered that you cheaped out and didn't run a circuit for the extra $25 dollars of material and minimal effort. (Not that 'they' would know that, but you would...)

Common practice to just run a 3-wire to the sink for the both as a give-in. Priced that way off the bat. That way you're covered if they up-grade the appliances after rough, or anytime in the future.

Guys:
Just a heads-up; check the nameplate on the DW. 9.1 amps total load; hmm....15 amp OCP
CHECK the nameplate before installing the CB,

GD's vary, 4.9 FLA, 8.25 FLA, etc.

Most guys around here run #12 to DW, 15 amp CB; #14 for disposal....H/R. Most DW are hard wired; disposals are probably a 50/50 mix.

Around here we just put the garbage disposal on one of the 2 required appliance circuits and the dishwasher usually gets its own 15 or 20 Amp circuit.It really works well-absolutely no callbacks!

Rhino - No other outlets.... Means no GB/DW, etc. Refers and ignitors for rangetops are an exception and Din rm/ pantry plugs.
