Patent ID: 7268307

Claim:
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.
