Control devices for tongue tais are generally known from foe prior art. In conventional ootdrol devices, the tongue rail is mechanically switched over with the aid of an electric or hydraulic switch drive, wherein a switch lock is also provided separately of the switch drive or integrated therein and a separate end position checking device is provided in any case. The switch lock serves for fixing the tongue mil in its respective end position. A plurality of control devices that are arranged offset in the longitudinal tail direction and include, If applicable, only the first ofthese control devices is usually connected to the drive unit ami the remaining conhol devices are mechanically coupled to the first control device and to one another in sock a way that: they are driven emildlrectfonally. The pipes, In: which the control or locking devices engage on the tongue rails, are respectively referred to as control or locking planes. AT SÖÖ3S& Al: discloses a switch control device.

However, the gfrangement of the coupling rod fosemhly outside foe Ifoek has the disadvantage Ihat this impairs the packing fvraeess. The packing process becomes even more complicated If coupling rod assemblies, which couple a plurality of control devices arranged olfoet in the longitudinal mil: ddëedon to one snothCh arc used In curved switches, Pependlng on the curve radius. a correapohding inclinationoffoe soap!ing md assenth|y pcpurs in curved switches SOcii that the space available for the packing process Is significantly reduced, US 2003d)42.UO AI discloses s device for controlling a rail switch that comprises a loupe device with two Stock rails and tongue rails assigned to the stock rails, wherein a plumlity of control devices are arranged offset in foe longitudinal rail are m^^itliítólycohpí^íforoMíífoófodriy means of a coupling ;rod assembly fo such a way that foey are driven epillmetiousilÿi wherein foe eouplng rod assembly respectively comprises between two adjacent control devises a sepamfo doubie rod assembly consistfog ot-two- parallel: and longitudinally nrnveáfele coupling rods that mechmucally couple foe two adjacent control devices to one another and extend between the two stock mils.
