Abstract
Improvements in the switching devices for electric heating installations fed to several voltages, in railway vehicles, characterized by having three switches for each current circuit, each of which can be placed in three contact positions, so that each The switch is open in one position and in each of the other two positions it communicates a point of the connection, fixed to said switch, with one of the other two points of the connection, and because in each current circuit four resistors are provided. heaters connected in series that, according to the relation to each other, are consecutively communicated in the order 2: 1: 1: 2 and, through the three switches, are connected to three different supply voltages, by known system, either in series or in parallel, keeping the ratio 3: 3 or 2: 2: 2, and for being provided the means to cut the connection between the circuits of current and the supply voltage, during regrouping.
