It is described a modular electric device (100) for controlling and/or distributing electricity, adapted to be wall mounted, comprising:
- a casing (120,140) made of an electrically insulating material;
- an actuation button (110);
- coupling elements (111-114,121-124) operatively interposed between the actuation button (110) and the casing (120,140), said coupling elements (111-114,121-124) being adapted and configured to couple the actuation button (110) to the casing (120,140) so that the actuation button (110) can take a first angular resting position and a second angular position different from the first angular resting position, respectively, said coupling elements (111-114,121-124 ) being also adapted to define a first rotation fulcrum (121A, 122A) for said actuation button (110);
- a tilting switching member (130) accommodated in the casing (120, 140);
- a first movable contact (131) arranged on the tilting switching member (130);
- a first fixed contact (161).
The actuation button (110) comprises a control portion (115) including an elastic return device (116) for returning the actuation button (110) to said first angular resting position, said control portion (115) being adapted and configured to contact and move the tilting switching member (130) by means of the elastic return device (116) so that, when the actuation button (110) takes the first angular resting position and the second angular position, the tilting switching member (130) takes:
a first angular configuration, in which the first movable contact (131) is separated from the first fixed contact (161); and
a second angular end-of-stroke configuration, in which the first movable contact (131) is in contact with the first fixed contact (161), respectively.
When the actuation button (110) takes said first angular resting position, the first rotation fulcrum (121A, 122A) is misaligned with respect to the elastic return device (116) .
