(54)	Direct current electric actuator, for domestic appliances in particular

(57) The electrically controlled actuator (10), in domestic appliances in particular, comprises
- a shell (12) realized in a single piece in ferromagnetic material, substantially shaped in C form and including a first and second lateral branch (14, 16) reciprocally opposed and interconnected by an intermediate portion (18);
- a coil (22) of conductor wire fixed to the shell (12) in such a way that its axis (A-A) extends in a direction substantially at right angles to the lateral branches (14, 16) of the shell (12); and
- a ferromagnetic nucleus (28) mounted movably with respect to the shell (12) in a manner axially translatable inside the coil (22) and suitable for passing from an axial rest position to an axial working position as an effect of excitation of the coil (22).
