Definitions
- switch-like circuit elements A further characteristic of such switch-like circuit elements is that they become non-conductive when the voltage drop across them is reduced to a predetermined amount.
- the switch elements when non-conductive serve for blocking a circuit against flow in either direction and, upon being triggered by an impulse, will conduct in one direction only until the voltage drop the-re across is reduced to a certain amount, whereupon they cease to be conductive and resume their blocking function.
- a circuit according to claim 1 which includes an impulse generator connected to said quenching switch and said working switch in controlling relation thereto.
