Abstract
A switch arm connector block for mounting a plurality of spring switchblades in a predetermined array for sequential cooperation with a timer cam and for providing a quick-disconnect connector for electrically connecting the blades to a wiring harness is disclosed. The connector block is formed by a plurality of insulating wafers which encapsulate a plurality of flat, parallel switchblades. The faces of the wafers are spaced from each other by projecting curbs around the perimeters of the wafers and window openings are provided in the wafers so that internal bussing may be provided in the block. End bussing is provided and the end bussing strips are covered by a protective cap having insulating fences for protecting the bussing strips.

A switch arm connector block for mounting a plurality of spring switchblades in a predetermined array for sequential cooperation with a timer cam and for providing a quick disconnect connector for electrically connecting the blades to a wiring harness comprising insulating block means, a plurality of flat, parallel switchblades passing through and having body portions encapsulated by said block means, said switchblades defining a first series of parallel planes and having longitudinal axes defining a second series of parallel planes transverse to said first series, said blades extending transversely as cantilevers from an end face of said insulating block means, tunnel means in said block for providing passageways along said first series of planes between and among the encapsulated switchblade body portion defining each of said first series of parallel planes, bussing means within said passageways electrically connecting at least two switchblades in at least one of said first series of parallel planes, means defining channels at said end face of said block means, and bussing means in said channels providing an electrical connection between a switchblade in one of said first series of parallel planes and a switchblade in another one of said first series of parallel planes.
A switch arm connector block for mounting a plurality of spring switchblades in a predetermined array for sequential cooperation with a timer cam and for providing a quick disconnect connector for electrically connecting the blades to a wiring harness comprising insulating block means, a plurality of flat, parallel switchblades passing through and having body portions encapsulated by said block means, said switchblades defining a first series of parallel planes and having longitudinal axes defining a second series of parallel planes transverse to said first series, tunnel means in said block for providing passageways along said first series of planes between and among the encapsulated switchblade body portions defining each of said first series of parallel planes, bussing means within said passageways electrically connecting at least two switchblades.
A switch arm connector block for mounting a plurality of spring switchblades in a predetermined array for sequential cooperation with a timer cam and for providing a quick-disconnect connector for electrically connecting the blades to a wiring harness comprising a plurality of insulating wafers, each wafer having a plurality of parallel switchblades having body portions encapsulated within a single planar rank, means for clamping and retaining said wafers in a stacked array so that each blade in a rank comprises a member of a planar file, a plurality of windows in each wafer exposing encapsulated body portions of each switchblade in said rank, bussing means between at least one pair of stacked wafers electrically connecting an exposed body portion of a switchblade to at least one other body portion of another switchblade in a planar rank.
