Abstract
An incremental travel encoder with an encoder part (11) and a sensor part for the sake of its economical production as a set-point value controller for operator equipment in motor vehicles, such as climate control systems, the sensor part has at least one electric switch with one fixed and one movable switch element for opening and closing a circuit for generating counting pulses, and the encoder part has a plurality of indexing members, which are disposed one after the other at the interval of an increment in the direction of motion of the encoder part. Upon each increment of the encoder part, one of the successive indexing members actuates the movable switch element in the direction of a temporary opening or closure of the electric switch.
