A toaster is provided with independent electric feeding for the classical two resistances which take part therein, so that the toasting effect may be supplied to only one of the two surfaces of the slice of bread, or to the two sides as is conventional. For this purpose, either two independent contactors are used, corresponding to the two resistances, which can act independently with the assistance of a movable wedge or be obliged to act simultaneously, in which case the resistances are fed through a diode, or else the said resistances are fed through two commutation transistors and from an electronic control and adjusting circuit provided with a temporizer and which is assisted by two push-buttons, one for selecting the resistances and the other for stop/release.
