What is the difference between this and polarity switching?

Just an idea I have been thinking about for awhile to eliminate a
stirring mechanism.
I know it isn't simple for the novice or practical for that mater.
Here is what I have been thinking. Set up a timing mechanism with a
relay, similar or equal to a polarity switch.
Set the on off times for 60 seconds or so. Now hook up the + or - to
one side of the relay so basically your shutting off the voltage for
60 seconds then back on for 60 seconds. Might have to adjust the
timing, maybe 120 seconds. Of course you also need some sort of
current limiting circuit. I already have a polarity switching device
with current limiting and a stirring device but if my stirring device
ever failed on me I thought this might work.
Any thoughts or other ideas.
TIA

PS. I post this same question on another list, just wanted to hit 2
bases. For those that see this post twice, please excuse.
