A dual pole relay can do this, and is often used this way in industrial machinery where safety is critical. |

Lol blueskull. No half measures for you! |

--- Quote from: IanB on March 09, 2019, 08:51:26 pm --- A single AND gate will do that, or a relay if you want a mechanical solution. A circuit like this is used all the time for the "push to start, push to stop" switching arrangement on machinery. (If you push the red button momentarily the machine will stop, and it won't start again until you push the green button.) --- End quote --- This circuit will do that. |

I suppose a thyristor would do and wouldn't require a reset after power-up. |
