A push button comprising:

a fixed portion which forms a frame;
a movable portion which can be moved in terms of translation between a rest position which is taken up in the absence of any actuation by a user and an actuation position which is taken up by pressing in the movable portion in relation to the fixed portion;
a commutator which pivots from a first state toward a second state when the movable portion is brought into the actuation position;
and
a flexible diaphragm which is arranged between the movable portion and the commutator, which is connected at the edges thereof to the fixed portion and which moves the movable portion into a rest position in the absence of any actuation by the user,
wherein the flexible diaphragm comprises:
a narrowing of the thickness thereof opposite the commutator,
an upper surface that carries the movable portion, and
deformation zones between portions adhesively bonded to the fixed portion and the upper surface, the deformation zones being at the periphery of the diaphragm and having a U-like cross section.
