ABSTRACT:
An outlet connection device transfers motion from outside to inside an explosion proof enclosure and includes a process for using a self-aligning bearing retained in a wall of the enclosure. The self-aligning bearing has flame paths selected to meet minimum safety requirements and contains a shaft for transferring either rotary, axial or joy-stick motion into the enclosure. In a rotary transfer arrangement an electric rotary switch is connected through a blade engaging the shaft passing through the self-aligning bearing.
