Abstract
Illuminated indicator circuit for electrical switching devices, particularly for switching devices in which there is an electrical circuit controlled between a closed circuit position and an open circuit position, said devices being in places of poor illumination, characterized in that it is connected, in shunt with the contacts of the apparatus cooperating with the mobile conductive element controlling the circuit, an indicator circuit comprising a discharge tube in gaseous atmosphere, of reduced power and a means limiting the intensity of the current derived by the indicator circuit, said tube and limiting means being connected to each other, so that when the circuit comprising said contacts is open, a small current is derived by the light indicator circuit illuminated the discharge tube, and when said circuit is closed, the element mobile driver joins the indicator circuit so that it is not it induces the illumination of the discharge tube, in combination with means for making visible from the outside the luminosity produced by the discharge tube.
