  We propose that the thermodynamics and the kinetics of state switching for
the asymptotically flat black hole enclosed by a cavity can be studied in terms
of the free energy landscape formalism. The generalized free energy for the
black hole enclosed by a cavity in the canonical ensemble is derived by using
the York's approach, where the temperature on the cavity and the charges inside
the cavity are kept as the fixed parameters. By quantifying the corresponding
free energy landscape, we obtain the phase diagrams for the black hole in
cavity, which reveal a Hawking-Page type transition for the uncharged black
hole and a Van der Waals type transition for the charged black hole. We further
assume that the dynamics of black hole state switching is mutually determined
by the gradient force and the stochastic force arising from the free energy
landscape and the thermal noises respectively. We then derive a recurrence
relation for the $n$-momentum of the first passage time distribution function,
which enables the calculation of the kinetic times characterized by the mean
first passage time and its relative fluctuation. Our analysis illustrates that
the kinetics of black hole state switching is determined by the ensemble
temperature and the barrier height on the free energy landscape.
