Abstract
A coil arrangement for a control circuit which controls the motion of a housing includes coils arranged as a printed circuit on a flexible foil. The coils serve as the control elements for the control circuit. The foil is H-shaped and the coils are arranged on the verticals of H. The portions of the verticals in contact with the cross-bar of the H-shaped foil support connecting-conductors which connect the coils on the individual verticals. An aperture, soldering terminals and connecting conductors are arranged on the cross-bar of the H. The cross-bar is affixed to the top or bottom of a block-shaped housing and the verticals of the H are folded against the sides of the housing.
