ABSTRACT:
The specification discloses a switching system for operating an incandescent lamp from a plurality of stations. The controlling switch at each station is wired in series with the lamp, and other control switches to form a single series circuit. Actuation of any single control switch produces a state change in the controlling circuitry so as to cause the lamp to increase or decrease in brightness. The rate at which the increase or decrease occurs is dependent upon the circuit values.
