What's the difference between a smart dimmer and a smart on/off switch?

Reviewer consensus

A smart dimmer lets you adjust brightness levels and is best paired with dimmable LED bulbs; an on/off switch only toggles power. The Lutron Diva and Sunnata are dimmers, while the Kasa HS200 and Tapo S505 are on/off switches. Pairing a non-dimmable load with a dimmer (or vice versa) can cause flicker or buzz.
