Magnetically actuated indicator

摘要

A magnetically actuated indicator includes a housing carrying an elongated permanent magnet for pivotal motion about a geometric axis which extends transversely to the geometric axis of the magnet. First and second poles are carried by the housing and are disposed in spaced relationship to each other and each is proximate to one end of the elongated permanent magnet in one angular position thereof. A coil is magnetically linked to the poles to change the polarity thereof and a stop prevents positioning of either end of the permanent magnet intermediate the two poles to insure consistant indications.
