| 摘要 |
The invention relates to magnetic indicators intended to give out an optical signal by reflected light. These indicators consist of two faces 1 and 2 forming an angle lying between zero and 90 DEG . A magnet 9 fixed on one support 3 situated on the bisector of the angle formed by the two faces, associated with the core 10 of the coil B, allows the indicator to rotate around an axis centred on 0. Application as a numerical and alphanumerical signalling element. <IMAGE>
