  2. Twilight switch - Wikipedia

    en.wikipedia.org/wiki/Twilight_switch

    Also, keep in mind that ignition is based solely on the amount of natural light present and not on the height of the sun, so "unwanted ignition" may occur, for example in the presence of compact clouds associated with a significant drop in ambient light on the sensor (e.g., when there is a storm). To avoid this, twilight switches can be ...

  7. Circuit breaker (overcurrent) - Wikipedia

    en.wikipedia.org/wiki/B50_circuit_breaker

    The current-carrying parts near the contacts provide easy deflection of the arc into the arc chutes by a magnetic force of a current path, although magnetic blowout coils or permanent magnets could also deflect the arc into the arc chute (used on circuit breakers for higher ratings). The number of plates in the arc chute is dependent on the ...
