I have two hots going into my breaker box (240volts). I want to put this switch before it reaches power to the box so I can cut power completely?

Without me being able to see it, I don’t know how you would get 240 v from it. I can see how you could get 120 v from each switch but to have 240 v, I’m sorry but I don’t know the answer.

How do you attach the face plate?

If you look close at the picture you can see a screw in the knob and two black “plates.” Remove the screw and knob and then you can put a plate on either side of whatever you are installing the switch on and put the knob and screw back in. I bought the box in the “frequently bought together” section on Amazon too. Baomain Master Switch Exterior Box SZW26-20 Work for Cam Switch SZW26-20/0-3.2 660V 20A 4 Position I hope this helps

I want to run a series of 20 amp rectifying diodes around a rotary switch to adjust voltage to a 12vdc, 250 watt motor. Will this switch work?

This should work for what you explained.

can I use it to switch from charging 2 12v batteries in parallel to using my 24 v trolling motor in serial?

Trolling motors can draw a lot of amperage, make sure you spec it correctly
