Abstract
Abstract A knob for mounting on the end of a shaft, especially a shaft of the type which extends through an opening in a panel and must be moved axially and rotated during operation thereof. The knob includes a hub, a shaft receiving socket formed in the hub and a web extending from the hub and terminating in a rim. The web is formed so as to be sufficiently flexible and deformable to permit the hub and the rim to move axially relative to each other. An annular dial may cover most of the flexible web. The knob and web may be formed in one piece, preferably of plastic or they may be separate pieces fastened together. When separate pieces, the knob may be plastic and the web may be spring steel.
