Abstract

Improved tuning block, characterized by being constituted by a series of switches (10) that are linked together through a conventional terminal strip (11), which houses inside a conventional mechanism, which allows that when the control is pressed of actuation (12) of one of these switches, unlocks the drive command that was retained, having itself installed, in a plane located in a position inferior to that of the switches (10) and located on the printed circuit (13). ), a series of adjustment potentiometers, each formed by a hollow prismatic housing (14), in which a threaded shaft (15) is installed that is supported freely allowing its rotation, axis (15) in which a cursor (16) is installed whose bore is provided with a thread whose pitch coincides with that of the shaft (15), cursor (16) in whose lower area has been provided with the corresponding mobile contact that will move along the action of the rotation of the shaft (15), such mobile contact running along its corresponding resistive track having joined in its base (17), a signaling device (18) equipped with a notch of slightly elliptical configuration, which inside will pass the lug (19) emerging from the upper face of the cursor (16), causing with its movement the horizontal movement of the tongue (20) with which the marker (18) ends.
