Abstract

Commutateur comprenant des contacts mobiles coopérant avec des contacts fixes ainsi qu'une entrée symétrique. Des curseurs 3a et 3b peuvent connecter l'entrée symétrique 2 aux paires de contacts, par exemple aux contacts 10, d au moins deux voies détournées 5a et 5b qui sont connectées aux conducteurs d'alimentation des dipôles. Application au déphasage de l'alimentation des groupes d'aériens directifs des antennes d'émission en ondes courtes.Switch comprising movable contacts cooperating with fixed contacts as well as a symmetrical input. Cursors 3a and 3b can connect the symmetrical input 2 to the pairs of contacts, for example to the contacts 10, d at least two diverted channels 5a and 5b which are connected to the supply conductors of the dipoles. Application to the phase shift of the power supply of the directional aerial groups of the shortwave transmission antennas.
