A base element and at least one switching element are included in an operator control device which may be disposed in a vehicle. By closing at least one electrical contact, the switching element is moveable from a first position into a second position relative to the base element. The operator control device can also include at least one pushbutton switch moveable relative to the base element between a position of rest and at least one activation position. The operator control device can further include at least one restoring element, formed of silicone and supported on the base element and on the pushbutton switch, which can be elastically deformed by moving the pushbutton switch from the position of rest into the activation position. Using the restoring element, the pushbutton switch can be moved from the activation position into the position of rest by relaxing the restoring element.

In one embodiment, a light guide includes an emitter and a light guide body optically coupled to the emitter. The light guide body may define a cylindrical body that tapers along an angled plane from a top end towards a bottom end. The bottom end may define a light entrance to the light guide body.

A key structure includes a casing, a covering member, a pressing element, a triggering post, a switch element. The casing has an opening. The opening is covered by the covering member. The pressing element is disposed within the opening and connected with the covering member. The pressing element includes a middle part and an extension part. The triggering post is installed on the middle part of the pressing element. The triggering post is extended in the direction toward the inner position of the casing. When an external force is applied to the middle part of the pressing element, the triggering post is moved toward the switch element to push the switch element. When the external force is applied to the extension part of the pressing element, the triggering post is correspondingly moved with the pressing element in an inclined manner to push the switch element.
