1. An operator control device for a motor vehicle, the operator control device comprising:
a base element;
a switching element moveable relative to the base element from a first position into a second position to thereby close at least one electrical contact;
a pushbutton switch moveable relative to the base element in a movement direction between a rest position and an activation position, the switching element moveable from the first position into the second position by moving the pushbutton switch from the rest position into the activation position, and
a silicone restoring element, supported on the base element and on the pushbutton switch, and elastically deformable by moving the pushbutton switch from the rest position into the activation position, the pushbutton switch moveable from the activation position into the rest position by at least partially relaxing the silicone restoring element,
the silicone restoring element having a shape of a truncated cone at least in a partial region, and having, on an end side facing the pushbutton switch, a recess which tapers along the movement direction in a direction pointing away from the pushbutton switch, the recess including:
a base,
a side wall adjoining the base, and
a wall region adjoining the side wall and extending obliquely with respect to the movement direction such that an end face of the wall region extends obliquely with respect to the movement direction.
