    Circuits Maxim MAX4094
    .. consists of a triangular-wave generator (U1a and U1b) and a comparator (U1c). U1a is configured as an integrator (or de-integrator) and U1b as a comparator with hysteresis. At power-up, the comparator's output voltage is assumed to ...

17. Momentary switch controls mains with latch-on and remote shutdown
    Peter Demchenko
    Circuits Nexperia 1N4448
    .. With the next press of the button, both transistors change their state, and the discharge current of C2 triggers SCR D6, de-energizing the relay and disconnecting the load. Due to the latching action of the SCR, this state cannot be reversed ...
