$begingroup$ @Majenko: The point is to reduce the high frequencies enough so that the active circuit in a voltage regulator can handle the remaining ones. Usually up to a few 10s of kHz is OK. For example, I often use some 950nH 600mOhm 200mA 0805 ferrites. With 22uF capacitance following these, you get one pole at 12 kHz from the R-C action, and another two poles at 35 …

Interesting how we all seem to move from smart bulbs to smart switches. I have found that using a smart switch build in close the light (connection, usually ceiling ) does add the required smart functionality. Leaving the old switches and function untouched. This greatly approves on the "wife approval factor" as well Eg.
