Abstract

The system comprises
a first and a second electrical terminal (1, 2);
a normally-open switch (10), arranged between the electrical terminals (1, 2) and intended to control the supply of current to consumer devices of the household electrical appliance which are connected to the second terminal (2), and including a movable contact (13) controlled by means of a bimetallic component (14);
a movable lock part (9) operatively coupled to the switch (10) and able, when the switch (10) is opened and closed, to take up a rest position and a work position, respectively, in which it enables and prevents, respectively, the opening of the door;
a third electrical terminal (3) intended to receive a supply voltage (V1-3);
a PCT resistive heating clement (50) arranged between the first terminal (1) and the third terminal (3), in thermal exchange contact with the bimetallic component (14) associated with the switch (10); and
an electric actuator device (25) set up to control, according to pre-established methods, the position of the movable lock part (9) and of the switch (10).
An electronic control circuit (30) is connected at its input to the first and third terminals (1, 3), and at its output to the actuator device (25), and is set up to drive the actuator device (25) according to predetermined characteristics of a supply and control voltage (V1-3) applied across the first and third terminals (1, 3).
