Abstract:
A shifting device for shifting between different operating states of a motor vehicle transmission, comprising:a gearshift lever mounted movably in a bracket and movable in a first direction between two shift gates and which can also be moved in a second direction along a first of said two shift gates into three shift positions; a signal transmitter comprising a contiguous active area for sending a transmitter signal; three sensors arranged at spaced locations from said signal transmitter and in the form of a triangle for detecting the transmitter signals; an evaluating device, said three sensors and said signal transmitter being movable in relation to one another by said gearshift lever and electric signals characterizing particular shift positions being sent by said three sensors at least indirectly to said evaluating device, putting the transmission into different operating states as a function of the electric signals, said active area of said signal transmitter having an extent at the site of said three sensors to flow through a rectangular area that is larger than or equal to the area of a rectangle in which a triangle of said three sensors can be congruently imaged, one side of said rectangle extending in parallel to said first shift gate, and all of said three sensors being in interaction with said transmitter signal in a first of said three shift positions.
