Circuit for controlling electric load via capacitor - uses electric control or drive with transistor, heat sensor or photocell between conductors joined to one plate of capacitor (NL 8.1.79)

摘要

Arrangement comprising capacitive circuit is designed to provide control of electric loads over long distances and to this end is connected to a conductive surface, the surface being safe to touch, via two mutually opposition-connected rectifiers, or to the conductors connected to the other plate of the capacitor having its first plate connected to the proposed arrangement. At least one electric control (driving) mechanism is connected between the conductors connected to the capacitor plate. Specif. the rectification elements are formed by one diode in each conductor; more specif. the control (driving) mechanism or mechanisms are formed out of mechanical switch(es), or out of electric circuit components such as transistors, heat-sensors or photo-cells.
