ABSTRACT:
A switch responsive to movements such as those occurring in a boat with respect to a horizontal plane is provided with electrical contacts arranged in a circular pattern in proximity to a fluid electrical conductor in a shallow annular chamber. The electrical contacts are arranged in two groups, the contacts of one group being positioned between the contacts of the other group so that an electrical circuit may be established by the fluid conductor between any of a number of pairs of the electrical contacts depending upon the tilting of the switch and the resultant positioning of the fluid conductor. Electrical circuits so established are useful in actuating devices, such as solenoids, and the movement of the cores thereof may be used to control stabilizing fins on a boat to overcome sideward tilting of the boat with respect to horizontal.
