Abstract

Un utensile portatile azionato da un motore elettrico (25), comprende almeno una impugnatura sulla quale è presente un sensore (16) in materiale conduttivo connesso ad un circuito elettronico per l'azionamento, alla rilevazione di una mano in presa su detta impugnatura, di mezzi (22) di consenso alla alimentazione del motore attraverso un interruttore manuale (13) di alimentazione. Il circuito elettronico comprende un generatore (18) inviante un segnale a relativamente alta frequenza all'ingresso di mezzi (19, 20) di misurazione della sua ampiezza. Il sensore (16) è connesso lungo il percorso di segnale fra generatore (18) e mezzi di misurazione (19, 20) così da indurre un trasferimento di segnale ad una mano in presa sulla impugnatura. In tale modo i mezzi di misurazione inviano comando di azionamento ai mezzi di consenso (22) alla rilevazione di un abbassamento della ampiezza del segnale prodotto dal detto trasferimento.
