Does it work the same when your Vref is variable? And you want a hysteresis around that variable voltage.

i am a little bit confused how dc input and AC feed back mix up at + , thanks !

These Schmitt-Tigger circuits are switching DC voltages between the two supply voltages of the operational amplifier. Actually one would use a special type of OpAmp, called a "comparator", for those types of circuits. Though they are depicted with the same circuit symbol, comparators are designed to switch very fast, whereas "classical" operational amplifiers are specifically designed for use as an amplifier for AC signals. I hope this answers your question.
