The Big Horn switch didn't come with instructions of any kind. The Shop Fox I purchased did, but either switch I can not get to work. Except the Shop Fox switch will run saw as long as I hold the button in. This is the Shop Fox instructions it came with. Frustrating
Pushing the "ON" button in should result in a "click" and it should stay in ..... no wires connected at all. If it doesn't click, it's defective.
Then checking with a continuity meter, the "ON" position should show continuity, and the "OFF" should show none between terminals 13 and 14. It is a mechanical type switch, not a magnetic type or latching switch.
If you wire it according to the diagram you drew and posted here, post no. 4, with a single pole ON/OFF switch, interrupting the black wire to the motor, as a test, the motor should run. If not, there are other issues. I now see that you are showing connections "across" the switch not up and down the switch.
Did you do as I suggested in post 5?
You NEED to check the continuity BOTH ways, but I think the switch operates "vertically", wires coming in and going out like most other switches and that's why the buttons are vertical!
Do not get confused by 220 V or 3 phase wiring. You only have 1 phase 120 V supply. Switch only the black wire, no others.
