.
Be aware that the A/C switch is a multi-component "part", with temperature control switch as well as a blower switch, probably best found as a complete assembly at a good auto wrecker, like Big M in Williams CA

Earlier this year Big M didn’t have one. I haven’t checked many other yards.
I have the switches, but the fan only works on one speed and I haven’t been able to determine if the temp is working.
I think the 55 Chrysler blower switch is 1626 810. I've checked Hiltop, Len Dawson and Mopar Mall. None seem to have a 1626 810. The two speeds is probably based on a resistor so it might be fixable if you can figure out what the low speed resistor is.
I think the temperature switch is a 1648 263 which was also used by 55 Plymouths and Dodges (that might expand your search a bit). I checked Hiltop, Len Dawson and Mopar Mall. None seem to have a 1648 263 either. No sure how the temp switch worked (presumably a variable resistor of some type).
Here is a link to a concise pdf for the 55-56 A/C parts that you might find handy:
