Abstract
A rotary position detector switch suitable for use in hydraulic fluid and having at least three stationary parallel conductive strips of tin plated low carbon steel intermittently over molded with intermediate portions exposed. An insulated rotor has a bus with spaced hardened steel pins with hemispherical ends slidably mounted thereon and bias springs connecting the pins to the bus. One stationary strip is completely exposed and is electrically common and in continuous contact with one pin. For each selected different rotor position combinations of two other pins contact different exposed portion of the remaining strips to give a discrete electrical indication, for each rotor position.
