<p>The system has two magnets (1, 2) aligned, dimensioned and arranged in two different housings (5, 6) in a rest position, so that magnetic field forces of the magnets acting on a reed switch (3) are compensated. The reed switch switches from an open state to a closed state or from the closed state to the open state when the housings are shifted or changed in a position relative to each other. One of the magnets is arranged in one of the housings in a movable manner. A wireless signal is triggered when the reed switch switches from the open state to the closed state. An independent claim is also included for a method for monitoring an object such as a door and a window.</p> |
