<p>The present invention relates to a switching device for low voltage systems comprising one or more accessory devices. The switching device according to the invention comprises a case containing at least one pair of contacts that can be reciprocally coupled/decoupled. The device furthermore comprises a containment structure to contain at least one accessory device of the switching device. Said structure is provided with means for interfacing with the accessory device which comprises a body that can be inserted in the containment structure. The accessory device also comprises coupling means to couple it to the containment structure and operating means which interact with the switching device via the interface means of the containment structure. The accessory device is also provided with disengagement means operatively connected to the coupling means. Said disengagement means, once activated, free the coupling means to permit extraction of the accessory device from the containment structure.</p> |
