Soft Latch Power Switch Circuit
https://www.electronics-lab.com/soft-latch-power-switch-circuit/
Dаvid Jones through his Youtube channel EEVblog described in detail how to design a cheap soft latch power switch circuit, using one push button switch to toggle your circuit power on and off with the following design requirements: Zero power when off. One on/off switch. Standalone(no MCU). General components only (Diodes, Transistors, ..ect). Minimal parts. […]
Latching power switch uses momentary-action pushbutton
https://www.electronics-lab.com/49033-2/
Anthony Smith @ edn.com published a push button latching circuit able to control a load with a single push of a button. The circuit in Figure 1 shows how you can use a simple, momentary-action, SPNO (single-pole, normally open) pushbutton switch to latch power to a load. Requiring just a handful of common, garden-variety components, […]
