Mechanisms of switching: Quasi-stationary response.
A At amplitudes below the critical range no switching occurs (A = 0.7). B Amplitude values within the critical range lead to switching (A = 1). C At amplitudes above the critical range the system undergoes periodic hysteretic switching (A = 1.3). D Bifurcation diagram of stationary states with critical values for saddle-node bifurcations (ηc1, ηc2) and the choice of model parameter (η0). E Normalized non-sinusoidal forcing over one period (A = 1), with minimum and maximum values indicated. Parameters: η = −10, , Δ = 2, τ = 20ms, f = 0.1Hz.
