Abstract

A shifting device is provided for shifting between different operating states of a motor vehicle transmission, with a gearshift lever ( ), which is mounted movably in a bracket and can be moved in a first direction between two shift gates (A, B). The gearshift lever ( ) can also be moved in a second direction along a first of the said two shift gates (A) into three said shift positions (X, Y, Z). A signal transmitter is provided for sending a transmitter signal ( ), and three said sensors ( ) are arranged at spaced locations from the signal transmitter and in the form of a triangle for detecting the transmitter signal ( ). The sensors ( ) and the signal transmitter can be moved in relation to one another by the gearshift lever ( ), and electric signals characterizing the particular shift position (X, Y, Z) are sent by the sensors ( ) at least indirectly to an evaluating device by which the transmission can be put into different operating states as a function of the electric signals. The signal transmitter at the site of the sensors ( ), sweeps an area that is larger than or equal to the area of a rectangle, in which the triangle can be congruently imaged. One side of the rectangle extends in parallel to the first shift gate (A). All three sensors ( ) are in interaction with the transmitter signal in a first of the three shift positions (X).
