Using two SCRs we can create a high-powered flip-flop capable of directly controlling 6 or 12 V lamps with currents of up to more than 1 amp. The circuit can be used to switch lamps from low current sensors or as a didactic application for classes. Eventually, capacitor C1 must be increased depending on the current of the lamps. Opposite electrolytes can be used, as this component must be depolarized. Depending on the current of the loads (lamps) the SCRs must be mounted on heat radiators.
