ABSTRACT:
The potentiometer is completely enclosed by a housing made of insulating material, of which material also the axle is made, so that the wiper is completely insulated. The potentiometer is dust-proof sealed and can either be adjusted manually or automatically with a screwdriver, or an additional axle can be inserted. The potentiometer can be mounted directly to the printed circuit board.
