    • A position sensor comprises a resistive element positionable on a first surface. A pair of leads are on the resistive element, the pair of leads adapted to supply a first voltage, such as by being grounded. An intermediate lead is positioned on the resistive element between the pair of leads, the intermediate lead being adapted to provide a second voltage. A contact element is positionable on a second surface, the contact element adapted to contact at least a portion of the resistive element to detect a voltage at a contact position, the detected voltage being related to the position or movement of the second surface relative to the first surface. In another version, a position sensor comprises a resistive element comprising first and second resistive strips. A plurality of leads are positioned on each resistive strip to provide a voltage to each resistive strip.
    • 位置传感器包括可定位在第一表面上的电阻元件。 一对引线位于电阻元件上,该对引线适于提供第一电压,例如通过接地。 中间引线位于一对引线之间的电阻元件上,中间引线适于提供第二电压。 接触元件可定位在第二表面上,接触元件适于接触电阻元件的至少一部分以检测接触位置处的电压,检测到的电压与第二表面相对于第二表面的位置或移动有关 第一表面。 在另一个版本中,位置传感器包括包括第一和第二电阻条的电阻元件。 多个引线位于每个电阻带上以向每个电阻带提供电压。
