Abstract: A detent apparatus for water temperature regulation of induction faucets includes a mixer located in a faucet and a swiveling mechanism located in the mixer. The swiveling mechanism has a rotary valve and a handle located outside the mixer and the faucet. The handle is fastened to an end seat located on one end of the rotary valve through a coupling member. The detent apparatus includes a detent portion preferably formed integrally with the mixer and located on the outer surface of the mixer body in a protrusive manner. The detent portion has a top end surface spaced beneath a bucking portion of the end seat at a selected distance. When the end seat is swiveled the bucking portion hits a left bucking angle or a right bucking angle of the top end surface thereby the swiveling angle of the end seat is confined within a limited range.
