3 Pos 240v Switch

Does anyone know of any 3 Position 240V switches rated for 30 or 40 amps? My thought is to install a switch AFTER the SSR in an electric HERMS to control two elements, just not at the same time. The 3 positions would be HLT on, OFF and BK on.

If not, any ideas on if its possible to do? Would the cycling fry the switch? I want to eliminate the need to unplug & plug the 240v outlets and just flip a switch to redirect power.

Good luck on that one! I did it with an additional SSR for cheaper than I could find it.

I'm trying to search for one, but while I'm doing that thought I'd throw out an alternative.

You could hit a 30 or 40A circuit breaker then from there you could do a 2 position switch. That way you have your off with the CB and the switch ensures only one operates at a time.

Here's one that looks like it would work. I have no clue how much this costs, but check it out if you wish. http://www.pc-s.com/Adobe/T225_a.pdf

How do you control the elements seperately? How did your rig turn out?

Thanks...I found a cam switch that looks like it'll work, but it was $130

I'll be posting this week, but everything is great!

what I do is have a SSR for each plug (HLT & kettle). Then I use a $5 DPDT 5vdc switch to move the output of the PID to the appropriate SSR.

Maybe I can get some pics up tonight. When I looked at all of the expense, the additional SSR made sense to me.

Cool...What size are your elements? How many amps is everything designed for?

Good move on the 2nd SSR. That is more cost effective then a 3 position switch & 2 relays.

Not only that, but just in case something goes wrong, I have a "Hot Spare" at the flip of a switch and the change of a plug. I made them both 40a for that reason.
