Abstract
A high reliability universal electrical swivel fabricated of insulative material virtually impervious to moisture or corrosive acid or alkaline vapors and having substantial flexural elasticity provides a conduit for an electrical conductor rotatable and tiltable about orthogonal axes. The swivel is adapted to retain its fixed position notwithstanding severe vibration and shock. Novel design minimizes stress on the internal conductor and its insulation thus minimizing the possibility of internal short circuits. The swivel components are especially adapted for economical mass manufacture and assembly.
