Abstract
An on/off switching component of a motor powered according to a first or a second polarity, connected in series with the motor. The switching component includes two head-to-tail connected cathode gate thyristors, and two diodes of same polarity. The two diodes have first same polarity terminals respectively connected to the gate of a respective one of the two cathode gate thyristors and second terminals connected together to a control terminal.
