Air conditioner disconnect circuit

Has anyone done this load-related AC compressor disconnect mod? It seems simple enough with the adjustable low voltage disconnect switch discussed in the article.

Unfortunately, the eLabtronics LVD switch appears to be unavailable from either Autospeed or eLabtronics. The articles are 3 years old, and clicking on purchase links leads to dead ends.

A search for adjustable LVD switches finds plenty of them, but they're all designed for battery switching in solar panel set-ups. None have the 0.1 to 4.5 volt trigger level needed to sense our TPS circuitry. I'm stuck. Any suggestions? I could probably build a circuit if given detailed directions.
