1. An input assembly comprising:
a support,
an input part mounted on the support along at least one direction of movement by means of a mounting device capable of vibrating, and
at least one light source,
wherein the input part has at least one input layer having an input surface intended to be touched by an operator,
wherein the input surface contains a display region to be backlit, and
the input assembly further has a light guide for guiding light of the light source towards the display region for backlighting the latter, and
wherein the light guide is disposed on the side of the input part facing away from the input surface, and
the input assembly further includes at least one of: a touch-detection device for detecting a touch on the input surface by the operator and an actuation detection device for detecting an actuation of the input part by the operator, and
an actuator for exciting a movement of the input part along the direction of movement by means of an electric control signal in order to generate a haptic feedback,
wherein the light guide is case arranged in the direction of action of an excitation of movement by the actuator;
wherein the light guide is formed from a material with a modulus of elasticity in a range of from 1 to 1000 N/mm2, and
wherein the input part has a constricted portion surrounding the input surface so that the input surface is mounted in an elastically yielding manner so that the input part is vibration-capable.
