This question already has an answer here:

The following one is working for restricting maximum number of authors for both citations and bibliography but how do we restrict to only citations.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[style=authoryear,maxnames=2]{biblatex}

\renewcommand*{\finalnamedelim}{\addspace\&\space}

\addbibresource{biblatex-examples.bib}

\begin{document}
Filler text \parencite{bertram,companion,jaffe,moraux}.
\printbibliography
\end{document}

    maxnames sets both maxcitenames and maxbibnames. If you want to have different threshholds, you need to set both. The same goes for minnames, mincitenames, and minbibnames. By default, minnames is set to 1 and maxnames is set to 3. – jon Mar 4 '14 at 5:02
