Signal actuator device for a position adjustment control

Signal actuator device for a position adjustment control, comprising:

• a support structure suitable for being connected to a position adjustment control, said support structure comprising a seat;
• a bottom driving shaft, turnably seated in said seat of the support structure, so as to couple to a control shaft;
• first torsional coupling means, integral with said bottom driving shaft and fully extending around said shaft;
• at least one first control cam torsionally coupled to said first torsional coupling means in a selective manner for adjusting an angular position relative to said bottom driving shaft;
• said at least one first cam being suitable for actuating, during rotation, an electrical device supported by said support structure;
• a top driving shaft, torsionally coupled to said bottom driving shaft in a selectively removable manner;
• second torsional coupling means, integral with said top driving shaft and fully extending around said shaft;
• at least one second control cam torsionally coupled to said second torsional coupling means in a selective manner for adjusting an angular position relative to said top removable driving shaft;
• said at least one second cam being suitable for actuating, during rotation, an electrical device supported by said support structure.
