We consider a multidimensional system of ordinary first-order differential equations with a nonlinearity of a non-ideal relay and a continuous periodic function of perturbation in the right-hand side. The system matrix has simple, real, nonzero eigenvalues and at least one is negative. We study continuous oscillatory solutions with two switching points in phase space and with the same time of return to each of these points on the discontinuity surface. The theorem of both the existence of the solution and its parameters is established. An example illustrating the obtained theoretical results is given.
