A set of removable combination cams has an assembly of identical rotary components mounted on a common rotary shaft and carrying removable cams for operation of switches. The rotary components are coupled together in such a manner that they can move relatively perpendicular to the axis of rotation, so that at least a portion of the periphery of one of the components is uncovered to allow fitting of the cam elements. Thus, the cam elements can be fitted without dismantling the assembly, and without changing the relative angular positioning of the rotary components, and without utilising resilient deformation of the materials employed, whilst retaining small axial dimensions for the assembly. |
