Abstract

A constant impedance T-attenuator, constituted by a frame of a generally prismatic-rectangular shape, wherein all the constitutive elements thereof are located, the latter consisting of a longitudinally positioned regulator 13, one of its ends forming a small head, there being between said head and the frame a thoric joint 16 and the other end constituting a driving head 17 with a diametrical fissure by the free end thereof, its inner stem being provided with two diametrically facing cuts, whilst the curve zones thereof are provided with some cuts which engage with corresponding ribs of the slider-holder. The attenuator is provided with three resistant tracks 5, 9, 10 on which some flanges of the slider contact, so that one of them 5 is fixed to a frame-constituting semibody and the outer protection body is fixed thereto, whilst the other two resistant tracks 9, 10 are located on the face being adjacent to the other resistant face and are joint to corresponding connection terminals.
