1. A jointed linkage support system made by a method comprising the steps of:
- providing a mold with a series of individual communicating cavities, a first set of the individual cavities configured to receive a first part, each of the first parts having a first contour, and a second, set of the individual cavities configured to form a second part, each of the second parts having a second contour, with the individual cavities of the first set positioned such that a plurality of individual cavities of the first set alternate with a plurality of individual cavities of the second set, and wherein at least one of the cavities of the first set is bisected by a plane of symmetry between the two adjacent cavities of the second set;
marking a plurality of the first parts from a first material having a first melting point;
placing the first parts in the first set of cavities with portions of the first parts extending into the second set of cavities;
introducing into the second set of cavities a second material having a second melting point which is lower than the first melting point to form the second part, wherein the second material is introduced into the second set of cavities at a temperature that is equal to or higher than the second melting point and lower than the first melting point;
allowing the second material to cool in the second cavities to form a plurality of movable joints with the portions of the first parts which extend into the second set of cavities, thereby molding a jointed linkage support system in which the first parts pivot with respect to the second parts without any of the second parts engaging an adjacent one of the second parts;
providing the mold with a third set of cavities;
marking a switch assembly material having a melting point greater than the second melting point;
placing the switch assembly in a cavity of the third set of cavities with a portion of the switch assembly extending into a cavity of the second set of cavities before the second material is introduced into the second set of cavities; and
introducing the second material into the second set of cavities to form movable joints with the first parts and the switch assembly.

Abstract
A system for molding a jointed linkage support system with joints that allow movement and bending in many directions and degrees of freedom. A chain-like linkage system made up of a series of joints is molded in a single step from materials having different melting temperatures in a series of alternating communicating mold cavities. The jointed linkage support system emerges from the mold fully assembled. An electrical switch may be provided within one of the joints between sleeves and rods whereby movement of the rod relative to the sleeve actuates the switch.
