Abstract

Improvements introduced in the installations of light signals for the regulation of urban traffic in places of danger, by means of lamps that close the passage when illuminated, leaving it open when it is turned off, facilities in which, in order to avoid dangerous traffic situations, when a lamp, other lamps are compulsorily connected, and in which are provided test switches to control the operation of the service of the lamps, characterized in that when a lamp is switched off, the test switches of the lamps that must be connected necessarily form a switch " multiple/y ", and this, together with the test switch of the lamp to be disconnected, an" o "switch, to whose output a control rest current is connected while, or the lamp itself is to be disconnected, or all the lamps interconnected by the switch "multiple/y and" or ", are running do.
