As the name suggests, a latch circuit activates/deactivates a switching element through one Set/Reset voltage input pulse and keeps it in that state. Because of that latch circuit are everywhere. They are part of other circuits or come in the form of power switches or latching relays. Let's learn all about them and build one!
