Abstract:
1. A rotary control device designed in particular to be attached to a handle of a remote control of a heavy construction machine, comprising: a casing designed to be fixedly attached to the handle, a movable actuation portion that can be rotated relative to the casing about an axis, first means for generating a proportional control signal based on the angular position of the movable actuation portion, comprising a movable portion moved by the actuation portion and a portion fixedly attached to the casing, the movable actuation portion being able to be moved by the operator in two opposite directions from a rest position against elastic means, which device also comprises second means for generating at least one signal of the on/off type delivering a first signal value when the actuation portion is oriented in a first direction relative to the rest position, beyond a first threshold, and delivering a second signal value when the actuation portion is oriented in a second direction relative to the rest position, beyond a second threshold.
