where to find 1/2" temp switch or adapter

[airdale94]

Here's some part #s for the fan switches. I've had really bad luck with Jet and Hypertech. Finally found the sweet spot 180 t-stat 180 fan switch from Hypertech. It lasted less than a year befor the fan switch went bad. Ordered a new one. It would turn on but not off. I am using the SW-505 from AutoZone and the 180 Hypertech t-stat. It comes on a little later than I would like but at least it shuts off. Plus it was only $9.00. I'm going to try a stock 195 t-stat when when I feel like "playing" with it again.
