Works
Very tactile, very nice.

So far, so good
A little odd that there are 5 lugs for a 3 way selector, requiring an extra jumper. My bigger concern is that the dial seems able to turn to multiple other positions with a variety of cross connections none of which i want to test. Not sure if my switch was faulty, damaged, or they just come that way. Undocumented feature we called it.

Pin-out Connection for 15Amp Version
There is no documentation, so for the 15-amp version (style-2) here are the connections Switch-Psn-1 OFF Switch-Psn-2 Pin-A connected to Pin-1 Switch-Psn-3 Pin-A connected to Pin-2 Switch-Psn-4 Pin-B connected to Pin-3 If you want a true 3-way switch, connect power to BOTH pin-A and pin-B. You will need a magnifying glass to read the pins on the case. I used nail-polish to mark the pins on the case. What I did was put 1,2,3 "dots" with nail-polish to indicate pins 1,2,3. Then I put 1,2 "dashes" with nail polish to indicate pins A,B. After about 5 minutes with a hair-dryer, they polish was dried and I could easily see which pin was which. Also, be aware: The 15-amp version does not mount with a big nut like the 10-amp version. You need two tiny screws to hold it in place (or maybe some hot glue).

4 of the wrong positions
Useless, the mechanism that engages the contacts. Engages the wrong contacts for an oil heater. All low settings so if you need on buy the 50 dollar one from the site.
