Abstract
To reliably hold a movable contact bridge carrier on a longitudinally slidable contact stem in position, even though subjected to severe vibration and shock, while still permitting free longitudinal movement of the stem carrying the contact carrier, the stem is passed through an opening formed in the magnetic yoke of the operating solenoid, and a clamping bushing, for example of tough, elastically deformable plastic, such as nylon, is placed in position to surround the stem where it passes through the opening, the bushing having spreader elements which extend radially outwardly to resiliently bear against the inner surface of the opening, the spreader elements merging into a cylindrical portion of the bushing surrounding the stem to hold the stem in centered, vibration and shock-absorbing position within the opening in which it is longitudinally movable.
