Maybe you could make a multiplexer. Here's something I ran across that talks about the problems of switching low voltage signals with nonmagical relays:

Hello all -
Has anyone implemented a cost effective solution for monitoring large quantities (~96) of thermal diodes for cryogenic temperature monitoring (down to 2K)? The solution proposed here is either the Lakeshore Model 218 or Model 224, both of which are ~$250/channel
... I was hoping to find something cheaper.
Any proven alternatives?
Thanks -
Ned
PS: I searched tech-talk and only found solutions for RTDs or thermocouples ...
