Abstract

A signal transmitter for setting the operating states of an automatic gear shifting mechanism having a selector, deflectable in at least three direction, and automatically returnable into a normal position X, by which a shift position R for engaging a reverse gear, a shift position N for the interruption of torque transmission in the gear change mechanism, a shift position D for engaging a forward gear are made. Additionally, the selector can be deflected in a direction for shift position N, N1, N2 for the interruption of torque transmission in the gear change mechanism starting from the normal position X, then another direction different from the first direction and its opposite direction for selecting other shift positions R or D starting from the shift positions N, N1, N2, and again deflected in the first direction after deflecting to other direction for selecting the other shift positions R or D.
