Device for energy supply to an electronic user interface of an electric household appliance

摘要

The device (20) has switching units switching power supply of an electric interface module (10) i.e. man-machine interface module, where the switching units are constituted by an electro mechanic relay (21). The switching units are placed in a mode in which the switching units are adopted to cut power supply of the interface module when an electric household appliance is in standby state. The switching units are adopted to reestablish cut off power supply to the interface module when an action is exerted by a user on a dedicated button (30) e.g. press button, in another mode.
