A solenoid has a coil energizable to displace an armature in one direction and a spring urging return of the armature in the other direction to a rest position in which an end of the armature engages a stop. The end of the armature has a conical projection machined thereon which projects from the end thereof. The stop is a resilient grommet having conical bore therein so that the rest position of the armature is defined by the spring urging the armature to the rest position with the conical projection of the armature resting in the conical bore of the stop to thereby provide noise-free and rattle-free positioning of the armature at the rest position.
