| 摘要 |
The specification discloses an electronic circuit which allows selective energization of electrical loads from a remote location by successive momentary interruptions of a common power source. In one embodiment, a ceiling fan and an attached light fixture are controlled from a single wall switch position, such that the first application of power energizes only the light circuit, a second application (following a momentary interruption) energizes only the fan circuit, and a third such application energizes both circuits at the same time.
