    摘要: An electronic control device (500) includes an input terminal (T1) connected to a second terminal of a switch (100) via an electrically conductive lead (110), an input circuit (200) connected to the input terminal via a signal line (SL), and a microcontroller (300) to detect whether the switch is in an electrically conducting state or an electrically non-conducting state based on an output signal from the input circuit, and to perform at least one process in accordance with a detected result. The input circuit includes a first resistor (201) connected to a supply voltage or ground and to the signal line, and a transient current circuit (210) connected to the supply voltage or ground and to the signal line, the transient current circuit including a second resistor (211) that allows a transient current to flow through the switch when the switch transitions from the electrically non-conducting state to the electrically conducting state.

    摘要: A process for automated contact wetting in a sensor circuit includes generating a first current through a contact (40) by sequencing a first circuit on, the first current exceeding a wetting threshold of the contact (40), and reducing current through the contact (40) to a second current by sequencing a second circuit on, the second current being below the wetting threshold.

    摘要: 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).

    摘要: In a rotary position sensor contact grease may be used without the risk of failure in contact making al very low temperatures. The rotary position sensor has a contact disk (16) driven in rotation about an axis (18). The sensor comprises a set of electrically conductive contact tracks (20, 22, 24) extending concentrically the axis on a face of the contact disk (16). A set of contact members (26, 28, 30) are held stationary opposite the contact disk (16) face in sliding engagement with the contact tracks. The contact tracks (20, 22, 24) are covered with a thin layer of contact grease, and a scraper member (32) is slidingly engaged with the contact tracks. Due to the action of the scraper member (32), the contact tracks are only covered with a thin film of contact grease that is safely penetrated by the contact members even in a state of high viscosity.

    摘要: Bei bisher bekannten Positionssensoren, insbesondere bei Sensoren zum Erfassen der Winkelstellung einer Drosselklappe einer Brennkraftmaschine, kann es nach längerer Betriebszeit bzw. bei besonders tiefen Temperaturen zu Funktionsstörungen kommen. Bei dem hier vorgeschlagenen Positionssensor sind die Kontaktbahnen (11) mit einer Schutzschicht (60), insbesondere Fett, beschichtet, wobei die Schutzschicht (60) an mindestens einer Stelle (Ruhezone) mindestens wesentlich dünner bzw. vollständig ausgespart ist. Der Positionssensor ist insbesondere zum Sensieren der Winkelstellung einer Drosselklappe einer Brennkraftmaschine eines Kraftfahrzeugs vorgesehen.
