    Abstract: The pilot circuit comprises an R-C network consisting of a condenser (Cx) inserted between a gate terminal of the MOS transistor (M) and ground and a resistance (Rx) for charging said condenser (Cx). In parallel with the resistance (Rx) there is placed an SCR circuit (Q1, Q2, Q3) with associated threshhold circuit (Q3, R1, R2, R3) which permits firing of the SCR circuit (Q1, Q2, Q3) when the charge voltage of the condenser (Cx) reaches a preset threshhold.
