Your "About Me" profile says 1979 F150, is this what you're working on?
Factory installed integral A/C is combined with the heater. The A/C controls are in the same panel as the heater controls.
What are you calling the control switch?
The A/C blower motor switch or the vacuum controlled selector valve assembly that mounts to the backside of the A/C/heater control panel?
This valve also includes the 'kicker' switch for the compressor.

Factory installed integral A/C is combined with the heater. The A/C controls are located in the same panel as the heater controls.
Three types of Ford A/C were available, factory installed and two types of dealer installed, but the pics you posted, do not match any of them.
Scroll down to see the pics I posted.
Upper pic: Factory installed.
Center Pic: Dealer installed Deluxe A/C.
Lower pic: Dealer installed Economy A/C. It's similar to what your truck has, but the panel contains the switches. Your switches are located below the panel.
It's possible that these two Economy A/C switches might work. The one on the left is the A/C blower switch, the one on the right is the A/C temperature control switch.

D4ZZ-19618-A .. A/C Temperature Control Switch (at the right) is the same: 1973/79 F100/350 & 1978/79 Bronco with Economy A/C / 1974/78 Mustang II with factory installed integral A/C
D1RY-19986-A .. Blower Switch (at the left) is the same: 1973/79 F100/350 & 1978/79 Bronco with Economy A/C / 1971/79 Econoline with dealer A/C / 1973/76 Torino with dealer A/C.
These switches are obsolete, but GREEN SALES CO. in Cincinnati OH has both of them: 800-543-4959.
Suggest you call and ask them to email pics of these two switches to you, so you can do a comparo.
NOTE: How far away are you from Estill or Hemingway or York SC? Three Ford dealers in these locations have the blower switch. If one is close by, you could go there and take a look-see.
Estill: TISON MOTOR CO. (803-625-2551) / Hemingway: HASELDEN BROTHERS (843-558-2134) / York: DICKERSON MOTOR CO. (803-684-4225).

Before heading there, call Tison and make sure they have the switch.
