The classification device (1) for classifying an input signal (S1;S2) which is an aperiodic vibration signal, comprises- a vibratory network (10) comprising a set of vibratory elements (11) and a set of coupling elements (12), each of the vibratory elements (11) being coupled to one or more of the other vibratory elements (11) by at least one of the coupling elements (12); and- a support (5) for supporting the network (10), at least one of the vibratory elements (11) being coupled to the support (5), in particular by at least one of the coupling elements (12).The vibratory network (10) has a shape such that the input signal (S1; S2) is classified to be a trigger signal (T) or to be a signal other than a trigger signal, wherein- the input signal (S1; S2) is classified to be a trigger signal (T) if, in reaction to coupling the input signal (S1; S2) to the classification device (1), a magnitude related to one of the vibratory elements (11) referred to as triggering element (11t) reaches or exceeds a threshold value (d0); and- the input signal (S1; S2) is classified to be signal other than a trigger signal if, in reaction to coupling the input signal (S1; S2) to the classification device (1), the magnitude remains smaller than the threshold value (d0).The magnitude is a displacement or a velocity or an acceleration of the triggering element (11t).The switching device (2) comprises such a classification device (1) and a switching element (20) operationally connected to the the classification device (1), to change a switching state of the switching element (20) when the magnitude reaches or exceeds the threshold value (d0).
