<p>Points switch for electrically operated crossover points forming part of electric toy railways. The switch unit consists of two see-saw switches, the see-saws of which are also bearings for rods (1,2) which do not directly influence the switches but control secondary current circuits. The rods extend lying flat from switch to switch in relation to the switch plate (3) with a contact metal located in each case between them for the secondary current circuits. Both metal contacts are positioned on a bridge plate (8) connecting the housing of the switches which extends parallel to the switch plate (3).</p> |
