Claim:
1. A method of manufacturing a magnet holder in an analogous or digital throttle position sensor for sensing the angle of a butterfly valve in a fuel supply unit of an internal combustion engine, comprising: a) making a throttle lever member adapted to be fixed to a shaft of the butterfly valve by injection molding, said throttle lever member having three parallel tubular members interconnected by an integral transverse connection, two of the parallel tubular members being equidistantly spaced from a third one of the parallel tubular members and having bottoms and constituting two recesses, each recess adapted to receive a magnet, and wherein the third one of the parallel tubular members is larger than the other two parallel tubular members and is adapted to receive the shaft of the butterfly valve; b) attaching at least two magnets to the throttle lever member; c) then inserting the magnets into the recesses; and d) retaining the at least two magnets in the recesses by staking the throttle lever member material located around entrances to the recesses to cover each magnet, wherein the throttle lever member material for staking is available in such an amount at the entrances to the recesses that the at least two magnets are completely covered by the throttle lever member material.
