There is described a control device (1) that allows to drive both AC solenoids and DC bistable solenoids. The control device (1) comprises power supply terminals (2, 3; 11, 12, 17) which may selectively be connected to an AC or DC voltage source, load terminals (4, 5) which may be connected to a driven solenoid (L), at least one triac device (T) connected in series to said driven solenoid (L), means (G) which may be controlled to switch on said triac (T). There are further provided selector means (S) interposed between said power supply terminals (2, 3; 11, 12, 17) and said load terminals (4, 5) to switch the control device (1) between a first configuration suitable for the power supply of an AC solenoid (L) and a second configuration suitable for the power supply of a DC bistable solenoid (L) and inverter means (A) which may be controlled to invert the voltage polarity at the load terminals (4, 5) with respect to that applied at the power supply terminals (2, 3; 11, 12, 17) when the control device (1) is selected in said second configuration (Fig. 1)
