Abstract
A device for detecting three states, namely ‘on’, ‘off’ and ‘triggered’ of an electric circuit breaker. The device includes a mobile magnetic device, movable between three positions corresponding to the three states of the circuit breaker, and at least one permanent magnet generating a magnetic field provided with magnetic field lines for driving two DIP switches via the magnetic effect. In each of the magnetic device's positions, the two DIP switches are controlled in either an open or closed position to form a specific combination representing one of the three states of the circuit breaker.
