Illuminated electronic doorbell

Claim 1

An illuminated doorbell switch including a system of continuously randomly illuminated lamps, comprising a housing having a front face upon which are projecting a plurality of neon lamps, an R-C circuit in circuit relation to each of the lamps, said R-C circuit and neon lamp forming a unit connected across common terminals, the unit being provided with the lamp in series with the parallel relationship of the resistance and capacitance, said common terminals being connected to a common source of current such as a battery, a pushbutton and doorbell arrangement means across said common source, said doorbell means being located centrally in the housing with respect to the location of said lamps projecting upon the surface thereof, and a DC-DC converter being interposed between the common terminals of said unit and the source of current therefor to provide increased application of voltage to the said units, said resistance being in series with the parallel relationship of the lamp and the capacitor, the housing being a single compact and packaged unit, so that each neon lamp flashes independently of each of the others and at a rate of approximately 3-6 flashes per second, the lamps being essentially circularly disposed about an area surrounding the doorbell button.
