ABSTRACT:
A control device contains two electromagnets (61, 62) in a respective current supply circuit (41, 44; 42, 44) which includes a biassed switch (20, 21) having first and second output terminals (2, 4), wherein the switches are biassed towards the first output terminal (2). When the magnets are moved to an active state against a biassing force, the switch in one circuit switches from its first (2) to its second terminal (4) to which the magnet is connected. The first and second terminals (2, 4) of the two switches (20, 21) are connected crosswise, so that a control signal (S1, S2) to the first circuit will initially energize the magnet of the second circuit, and vice versa, wherein the magnet remains in an active state if switching of the switches takes place within the time period taken for one of the magnets to leave its activated state after deactivation, i.e. when the two control signals (S1, S2) are both applied within this time period. The control device may be used, for instance, for the two-hand control of pneumatic clutches and brakes in an eccentric press.
