ABSTRACT:
A telephone hook switch is manufactured by first molding a moldable insulating material into two block portions and an integral bridge. The block portions have a common back surface, adjacent parallel side surfaces having opposed and aligned back edges interconnected by the bridge, a pair of pivot members aligned on a plane perpendicular to the side surfaces and equally spaced therefrom, and slots formed in the respective block portions parallel to the side surfaces and spaced from the pivot members. The bridge has a thin portion bisecting the distance between the side surfaces. Contact members of the switch are snugly placed in predetermined ones of the slots and one of the block portions is folded at the thin portion of the bridge towards the other with the back surfaces of the respective block portions brought into substantial contact with each other. A lever member of the switch is mounted on the pivot members.
