发明名称 Remote switch contact quality maintenance
摘要 A system for maintaining integrity of a switch contact includes a first resistor-capacitor circuit, a second resistor-capacitor circuit, and a control switch. The first resistor-capacitor circuit is connected to an output of the switch contact and includes a first resistor and a first capacitor. Upon closing of the switch contact, a first wetting current flows through the switch contact. The second resistor-capacitor circuit includes a second resistor and a second capacitor. The control switch is connected between the output of the switch contact and the second resistor-capacitor circuit and is selectively closable to generate a second wetting current through the switch contact. The control switch may be operated as needed to maintain the integrity of the mechanical switch contact.
