Abstract

An electrical circuit module in which structural elements of the circuit module are foamed or cast over with synthetic resin. At least one component is located in the interior of the resin and has an actuating shaft allowing adjustment of the component. An extension shaft that is rotationally symmetrical and has a driver is coupled to the actuating shaft. The extension shaft has a rotation-symmetrical bead and is embedded in the synthetic resin in a positive-fitting manner. The extension shaft also has an adjustment and protruding to the outside of the resin, and a surface which forms a separation layer toward the resin.
