<p>With these devices a relative H F (high frequency) electric current applicable to the human body is generated by means of an active electrode and a neutral or return electrode, whose electrodes are connected to the transformer of the output stage of the corresponding circuit. The invention is characterised by the coil of the output transformer having on the secondary winding, besides connections for the end terminals for connecting the neutral or return electrode and an active metallic electrode with electrically insulating cover, an intermediate terminal for connecting an active metallic electrode without insulating cover, whose terminal is furnished with an adequate very reduced impedance with an average which adapts only and exclusively to the different sizes of said metallic electrodes without metallic cover which are used. <IMAGE></p> |
