We propose a two-state electric field-driven high-temperature single-molecule switch based on a dipolar molecule enclosed inside ellipsoidal fullerene C70. We show that the two low-energy minima of the molecular dipole inside C70 cage provide distinguishable molecular states of the system that can be can be switched by application of an external electric potential. To read the state of the switch we showed that there are two possible methods on the basis of spectroscopy  and electric conductance. The latter method is possible because polar endohedral molecules can induce strong polarization in the electron density of C70, thus turn it to a single-molecule rectifier.
