Weird cotter pin in hot water switch.
OK, so this is a new one on me. As you an see from the pictures, I have a hot water heater with a cotter pin holding the switch in the off position. I also have a switch inside that turns the electric water heating element on and off. My question is what purpose does it serve to hold the switch in the off position? What will happen if I remove the pin and turn it on? Does the inside switch bypass this on-heater switch requiring it to stay off?

Yes, you do have to have that switch in the on position as well as the electric switch inside too for the ele tric element to work in your swdel model suburban

If you will look in the FAQ subsection, I have a thread about the suburban swde and swdel water heaters titled "suburbans electric switch and much more".
It will explain the two electric switches for the swdel model you have

I think that post should be a sticky.

When you take the time to read the thread it fully explains it. The switch on the tank only controls the electric heating element.
The switches inside for the swdel model has one that goes to the electric heating element also, and another for the propane heating method. They are independent heating modes and you can use one or both at the same time.
Again fully explained in the link

Thanks, but I was asking if I had the correct interpretation of what I read because it is very long and complicated.
Could you please offer a more helpful answer rather than RTFM?

Yes, you figured it out. It keeps you from accidentally burning the element out, usually at the beginning of the next season.
As long as you remember to turn it off before you drain the system, of course.

As wmtire pointed out in post #2, you need both switches on for the water heater to heat on electric.

Geez... lighten up.
Folks are trying to help you, help yourself.
If it was TLDR, that's on you.
You had your answer in post #2 about needing both switches on.
And your assumption about the cotter pin is correct.
RFTM are pretty harsh words... no need to use profanity.

I think it is giving you one last warning to be sure it is filled with water before turning it on and frying the heating element. My motorhome I used to own had one! Yes, I did fry one heating element before figuring this out!

I for one did not know what TLDR meant, so I had to google it. This was the 2nd result.

I learn something new every day. I also did not know what RTFM was, but that one I was able to figure out without google.
