Isolation circuit for detecting the state of a line connected switch |
February 2, 1993 |
| The circuit includes a capacitor (C1) and a resistor (R1) connected in series and interconnected with the switch to sense which phase of the line to which the switch's wiper is connected. The impedance of the series circuit of C1 and R1 is very high, so that when the switch is open, it |
