This circuit uses two electromechanical relays to realize a sequential switch that’s permanently resistant to electrical disturbance, remembering its state despite power failure and consuming energy ...

Switching the growth mode of inorganic crystals layer-by-layer has been a longstanding goal in materials science, inspired by the extraordinary natural nanocomposites comprising the biominerals found ...

I know, I know—discussing the subject of a relay-based sequence switch in the age of omnipresent microprocessors seems to be a waste of time. After all, relays have been in use for many years. Is it ...
