Long time lurker, first time poster.
This piqued my interest, as it relates to my upcoming electric build. I've been looking to switch between two sensors, as well (RTDs). I don't see why it wouldn't work, assuming the switch has minimal intrinsic resistance. Temperature is determined by the PID by detecting the resistance between the two wires of the RTD (which varies with temperature changes in the probe). So long as the switch doesn't add resistance (and I would hope it doesn't...), it shouldn't change the temperature reading, should it?
If you were using a thermocouple type sensor, then I think it would be a different story.
