Background. Inertia switches serve in pilotless vehicles for electrical switching. The switches triggering takes place generally when reached the integral of linear acceleration at which the vehicle travels in the space. Materials and methods. For integration of the linear acceleration both magnetic and hydraulic dampers are customary used. In several cases hydraulic dampers are more suitable in the view of inertia switchers design simplification. Results and conclusions. The work presents the results of developed mathematical model of the inertia switch: formulated differential equations describing movement of mobile design elements and motion start conditions, as well. A mathematical model is worked up to estimate the parameters of both functioning and triggering the inertia switch.
