To me it sounded like another facet of daas torah namely accepting anything from a rosh yeshiva wether it makes sense or not.
If your rav said the KosherSwitch was assur, would say, “but that doesn’t make sense – you’re just moving an isolated piece of plastic!”? Or perhaps you would try to understand, but not say that ” it doesn’t make sense”.
Yes, that is part of daas Torah, accepting, just as we do in halachic matters, that something may be true despite our not understanding it.
