Abstract
Abstract An electric potentiometer used for conversion of a rotating movement into an electrical value. The potentiometer has a wiper passing across a resistance path and, on the other end, the wiper is rotatingly coupled with a bearing shaft. The resistance path is disposed on a mounting plate next to which is disposed on the intake pipe wall an elongated plug, made of plastic by injection molding, in which are embedded contact prongs, which are connected on the other side in an electrically conducting manner with connecting contacts extending generally perpendicular to the contact prongs.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
104 words
An electric potentiometer mounted on a wall of an intake pipe of an internal combustion engine, said electrical potentiometer including a resistance path disposed generally parallel to a mounting plate, an elongated plug made as an injection molded plastic part and having equally spaced prongs embedded in said plastic part and electrical connecting contacts, partially embedded in the plastic connected to said prongs, characterized in that said elongated plug is connected with an exterior wall surface of said intake pipe with said prongs extending in an outward direction relative to said intake pipe and the connecting contacts extend generally perpendicularly to said contact prongs.
Claim 2
Dependent Claim
