ABSTRACT:
A diode switching system for use with an electrographic writing system is disclosed. The switching system has a high storage charge diode with a capacitor connected to its anode which defines an output. Once the diode is charged, application of a large drive voltage to the free end of the capacitor will short the voltage through the diode due to the stored charge of the diode, thus preventing the stylus from writing. When the diode has not been charged, application of a large drive voltage will be coupled through the capacitor thus powering the writing stylus.
