<p>Device generating an electric coincidence signal when a body pivoting with respect to a horizontal rotation axis takes up a predetermined angular position to be characterized, with respect to said axis. According to the present invention, the device comprises a curved rolling track (2a), fixed to the body (K), of which the plane is perpendicular to the rotation axis (9) of the body (K) and which has for each angular position to be characterized two electrically conducting segments (4, 4) isolated from each other, separated by a slot and bridged, when the body (k) reaches the angular position, by an electrically conducting rolling body (5) rolling in the rolling track (2a). The present device is characterized by a simple, solid and reliable construction, as well as a high triggering power. </p> |
