Abstract
A visual position indicator has a stator and a rotor with angularly displaced eccentricities for engaging corresponding spring biased actuators with magnets. Depending on the rotor position relative to the stator, one or more of the actuators is moved to a position whereat the field of its respective magnet can operate a magnetic switch disposed in a hermetically sealed housing. A decoder connected to the switches can produce a signal indicative of rotor position.
