An electrical functional device for use in the field of aviation, for example, a safety switch, is described. The functional device has a housing out of which a cylindrical fixing neck projects. The fixing neck contains, on an outer circumference thereof, a fine-pitch threading for screwing on a nut, and carries, at a distance from the end thereof that is attached to the housing, a radially protruding bearing flange. The bearing flange serves to hold the device in a fixed position, in which the fixing neck projects through a fastening hole of a wall element and is held therein against the bearing flange by a nut. The fixing neck is a one-piece part made out of plastic. It contains, between the end of the threading thereof and the bearing flange, an unthreaded shaft area, which is coaxial in relation to the fixing neck.

The invention is based on the recognition that filter bandwidth can be traded for improved out-of-band rejection.
