Ditch The Switch: A Soft Latching Circuit Roundup | Hackaday 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. Soft latching with button sensing and controlled power off My idea was to use a soft latch circuit. Q1 is turned off by the current flowing through R1 and R2 by default. When button 1 is pressed, current flows through Q1, R2, button 1, R3 and to GND. Q1, being activated, in turn activated Q3, which should permanently activate Q1. To "turn Q1 off" I power Q4 to shorten Q3 to GND. Two Button On Off Latching Circuit | All About Circuits Ideally this will be a 12V circuit. I can find lots of circuits that use a single push button to turn the pump on and off but I want to use two. One micro switch will be at the low point and one will be at the high point. Can anyone point me in the direction of a circuit that will achieve this. Thanks in advance. Jason Simple soft power latch circuit... Page 1 EEVblog Simple soft power latch circuit... Page 1.
