ac switch help

OK this is my first time posting here but i need MAJOR help with something. I have an aftermarket ac put in my 88 camaro. The other day the switch in the ac controls burnt out. Well i found a new one but it is rare so it is gonna cost me $45.  What is special about it is that it has both the blower speed and the temp control on the one switch. I can buy a switch without the temp control for $17 so im trying to figure a way to bypass the temp control. There are two wires going to the temp control. One seems to be a 12V and the other goes to the compressor and tell it to let more or less freon throught the lines making it cooler or hotter when the AC is on.  It DOESNT control whether the AC is on, just how hot or cold it gets. In the temp control area there seems to be a resistor that is disc shaped. When you turn the temp control knob it rotates the disc.

This is what i figure:

If the temp control, controls how much power goes to compressor then if i was to bypass the temp control and connect the two wires then it would allow full power to the compressor, just like having the knob at full power (coldest). My only concern is if there was a max being alowed through the temp control. i dont want to connect the two wires and allow too much power through and burn something out.  How do i find what the max is (if any)? and will my idea work?
