1. A selector lever assembly for selecting and shifting to various driving modes in a vehicle transmission, comprising:
a rotary switch rotatably mounted in a housing,
wherein the driving modes are assigned along a rotational range, and separated from one another by a latching contour that can be felt by a driver; and
a locking contour configured to selectively block a rotation of the rotary switch,
wherein the locking contour and latching contour are integrally formed on the rotary switch,
wherein the integral rotary switch has a disk-shaped body, which has a knob for manipulation thereof formed on a first axial side, and a sleeve formed on a second axial side, with which it can be rotatably mounted on the housing,
wherein the latching contour has a dedicated spring-loaded latching pin fixed in place on the housing, wherein the latching pin functionally interacts with the latching contour to generate a latching effect that the driver can feel during the rotation of the rotary switch,
wherein the locking contour is formed by a plurality of stop regions on the disk-shaped body of the rotary switch,
wherein each stop region has an adjacent recess on the disk-shaped body of the rotary switch, and
wherein each stop region is connected radially on an outside of the disk-shaped body to a wave-shaped annular contour and radially on an inside of the disk-shaped body to a mechanically stabilizing annular region on the disk-shaped body.
