ABSTRACT:
The present invention relates to a detent mechanism for a rotatable body to bias the body in any of a multiplicity of predetermined angular positions. The body has a projecting element of polygon shape, extending from its rear end. The element defines a cavity in it. A projection extends inwardly from the wall of the cavity. The projection cooperates with a stop to limit the angular rotation of the body. The device is designed to permit different polygons to be used so that the number of angular positions at which the body stops may be changed. The detent mechanism is shown in conjunction with a microwave drum attenuator since it is desirable, in such an attenuator to reduce undesirable forces on the drum attenuator.
