Abstract

Method for operating selector equipment between several voltages, to govern the grouping of electrical appliances capable of being operated with dc or ac systems of different voltages, in which electronic commutating members with tilting behavior are applied to the proportional voltage of a voltage divider which conducts the operating voltage, and which on the output side govern grouping equipment, especially for the grouping of heating resistances in railway vehicles, characterized in that the proportional voltage appearing in the divider of the voltage is differentiated in different selection stages connected according to the frequencies that can be expected, including the null frequency, that is, the dc voltage, and the grouping equipment is governed by means of the determined frequency.
