ABSTRACT:
A novelty button assembly provides buttons with a variety of indicia on the face of the button and an unlimited location of the blinking light in the face of the button. An electronic circuit is adapted to drive a light emitting diode with a current pulse of very short duration to permit the use of a small battery and to provide long battery life. A capacitor is used in a novel high efficiency oscillator circuit only in the determination of blinking rate and battery current duty cycle, allowing the use of a wide variety of smaller value capacitors that lend themselves to microelectronic packaging desirable in flasher button assemblies. The pin used to fasten the flasher button assembly to the clothing of a wearer also serves as the electrical switch to turn the flashing button assembly on and off.
