Abstract
A magnetic flip-flop circuit, predominantly used for hydrophone preamplifs, which allows switching capabilities at a remote location while minimizing the number of conductors. In particular, the circuitry is a magnetic flip-flop system which has a multiple-pole, double-throw latching magnetic relay in combination with a single-pole, nonlatching magnetic relay. The combination is coupled to allow a switching of the magnetic latching relay by merely removing the voltage from a single conductor.
