🌀 Enhance System Performance with Four Seasons 36646 System Mounted Binary Pressure Switch Review

This switch was a complete disappointment for my automotive project. The mounting was terrible and the pressure readings were inaccurate. The only positive was that it was affordable. However, the cons outweighed any possible pros. I would not recommend this switch to anyone.

After a little modification everything worked. The shoulder was too long and wouldn't screw onto the fitting, trimmed it down with a grinder and it fitted well.

A great addition to your R-12 to R134 conversion project. It extends the life of your compressor and actually helps lower the air conditioning temperature in your car.
