This paper determines the spectrum of $\epsilon $-switchable $G$-design where $G$ is a kite (a triangle with an edge attached) and $\epsilon $ takes $t$-edge, $h$-edge and $l$-edge. \itemrv{~} \itemcc{} \itemut{complete multipartite graph; $G$-design; switchable kite system; group divisible design} \itemli{} \end
