ABSTRACT:
A variable electric capacitor has two electrode units consisting of a plurality of plates or a single spirally wound plate with several turns. The plates or turns have opposite lateral edges, one of which is free and the other is fixed to a support. The plates or turns of the two electrode units are interleaved and to change their mesh, one electrode unit is movable relative to the other. Each electrode unit has locating elements for the free lateral edge of plate or turn of the other electrode unit. These locating elements adjoin the supports of the electrode unit concerned and are formed to hold the free lateral edge of each plate or turn of the other electrode unit in a predetermined position when both electrode units are in their maximum mesh position.
