Abstract

L'invention a pour objet un dispositif électrique variable comprenant deux composants, la position de l'un d'entre eux étant réglable linéairement par rapport à l'autre au moyen d'un mécanisme de réglage. Le dispositif selon l'invention comprend une gorge en forme de spirale 28 reliée à l'un 24 des composants 10, 24, l'autre composant 10 étant fixe par rapport à un axe 25 autour duquel la gorge en forme de spirale 28 peut tourner. Application aux << trimmers >>.
