A push-button switch includes: a substrate (2), on which an electric circuit (3) is provided; a cursor (7) movable along an actuation direction (D) with a stroke between a rest position and a pressed position; a pad (4) made of an elastic polymeric material applied to the substrate (2); a pre-loading device (10) configured to provide a pre-loading force to the cursor (7) along the actuation direction (D) toward the rest position; and a dome-shaped metal switch member (8) housed directly on the substrate (2) in a seat (21) between the pad (4) and the substrate (2). The cursor (7) has a base (7a) coupled to the pre-loading device (10) and is provided with an actuator member (20) extending from the base (7a) parallel to the actuation direction (D) and configured to actuate the switch member (8). The actuator member (20) is aligned to the switch member (8) and is misaligned with respect to the pre-loading device (10).
