Abstract

A selector lever device for selecting and switching different driving modes in a vehicle transmission is proposed, the selector lever device having a rotary switch (1) rotatably supported in a housing, wherein the driving modes are associated with rotation angle ranges and are respectively separated from each other by locking contours in a manner perceptible to the driver, wherein the rotational movement of the rotary switch (1) can be locked via the locking contour, and wherein the rotary switch (1) is implemented integrally with the locking contour and the locking contour.
