Abstract
A system (10) for maintaining integrity of a switch contact (12) includes a first resistor-capacitor circuit (16), a second resistor-capacitor circuit (18), and a control switch (24). The first resistor-capacitor circuit (16) is connected to an output of the switch contact (12) and includes a first resistor and a first capacitor. Upon closing of the switch contact (12), a first wetting current flows through the switch contact (12). The second resistor-capacitor circuit (18) includes a second resistor and a second capacitor. The control switch (24) is connected between the output of the switch contact (12) and the second resistor-capacitor circuit (18) and is selectively closable to generate a second wetting current through the switch contact (12). The control switch (24) may be operated as needed to maintain the integrity of the mechanical switch contact (12).
