  We explore the control and switching of the entangled spin states of
multi-spin particle qubit coupled to an electron using a three-particle spin
model described by $S_i$ ($i=1,2,3$), in which $S_1=\tfrac{1}{2}$ is an
electron and $S_{2,3}$ can have any spin with both exchange coupling and
magnetic anisotropy. We derive a general formula for the existence of a
switching (DJ) resonance for any spin $S_{2,3}$. We further contrast the
entanglement switching mechanisms for the $S_{2,3}=\tfrac{1}{2}$ and
$S_{2,3}=1$ spin models. We find that while the onsite magnetic anisotropy in
the case of $S_{2,3}>\tfrac{1}{2}$ allows full control of their spin states via
interaction with $S_1$, in order to achieve acceptable control of a Bloch
vector within the $S_{2,3}=\tfrac{1}{2}$ model, additional mechanisms, such as
anisotropic exchange coupling, are required.
