| Zusammenfassung: | The utility model relates to an electricity-saving switch which can extend the service life of a filament. After the switch is on, electric currents flow across a diode, and a weak electric current flows through the filament; as the switch continues acting, the switch is fully on. The structural switch can give the filament a weak electric current in advance, which reduces the instant thermal shock of the electric currents to the filament, and extends the service life of the filament. In addition, because switched electric currents are reduced, the electricity-saving effect is achieved. |
