In this paper, the stability and bifurcation of motions in a fermi oscillator under dual excitations are presented using the theory of discontinuous dynamical systems. The analytical conditions for motion switching in such a fermi-oscillator are obtained, and the generic mappings are introduced to describe the periodic and chaotic motions for such oscillator. Bifurcation scenarios for periodic and chaotic motions are presented together with analytical predictions of periodic motions. Finally, numerical illustrations of periodic and chaotic motions in such an oscillator are given. In addition, the flutter oscillations of such an oscillator are presented through the switching section for the Neimark bifurcation.
