As for the rest of what you said, I think that the low power consumption of soft latching circuits is usually acceptable, but for very low and high-power circuits a physical switch is best.

Figure 1 illustrates a variety of driving circuits, depending on the input-signal-logic levels, their coding, and the magnitude of the available supply voltages. The circuits in figure 1a through ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Figure 1 Circuit converts momentary action push switch into latching power switch.. To understand how the circuit operates, assume that the DC power supply, +V S, has just been applied, capacitor C1 ...

Measured waveforms from the latch circuit during an output overvoltage event demonstrate how the circuit operates . The power-supply output voltage is configured for a nominal 35 V.

Electronic devices use components like resistors, capacitors, transistors, diodes, & ICs. Circuit diagrams use symbols to represent these, enabling engineers worldwide to communicate & understand ...
