What is the difference between Single Switch and Smart Loop?

With Single Switch, you can schedule a design change on one instance and after the set duration, the catalog will revert to its original design.

For eg.
If you want to run a Christmas sale from the 15th to the 26th of December, you would set up a Single Switch to start on the 15th of December and end on the 26th of December, at 11 PM. At 11 PM, the design will revert back to whatever design the catalog had before it changed. 

However, with Smart Loop, you can set up a series of designs for your catalog ad/feed ad to ‘loop’ through at pre-defined intervals.
Note: A Smart Loop goes on infinitely till it is ended manually.

Here’s a quick demo of the Smart Loop:
