Abstract

Electric circuits gifting apparatus comprising: a magnetic contact and a permanent bar magnet, separated from each other; a non-oriented magnetic tab mounted on one end of the apparatus, and which, through its free end, enters the space between the contact and the permanent magnet in such a way that the free end of the tab is normally applied against the magnet and is maintained a prefixed gap or space between the contact and said free end of the tongue, and a coil to produce a magnetic flux along the tongue in response to an electrical signal, in order to cause relative movement of the contact and said end free of the tongue, to close the slit; characterized in that the magnetic axis of the bar magnet forms substantially right angles with the magnetic flux produced by the flux generating elements of the tongue, the contact and the slit.
