ABSTRACT:
A clothes washing machine including a washing tub containing a drum and a door for closing the drum provided with a door interlock arrangement. The door interlock arrangement includes an electromagnet (1), a main sliding element (4), a door catch (5), a spring (6) forcing said main sliding element back to its resting position, an inclined plane (9) of the door catch, a switch (2) actuated by the main sliding element (4), a device (10) that is electrically energized during spin-extraction phases only, a peg (11) projecting from the device (10) when the latter is not energized, and a recess (12) for accommodating the projecting peg (11) in the main sliding element (4). The main sliding element (4) also includes a recess (8) for accommodating the door catch (5). A secondary sliding element (3) is provided so as to be able to slide transversely with respect to the main sliding element (4). A spring (7) acts upon the secondary sliding element (3), and an upper edge (13) of the main sliding element (4) is capable of cooperating by interference with a downward projection (14) of the secondary sliding element (3).
