Just to give additional information on the Equipment. It is a GE Transformer Three Phase, Pad Mounted Distribution Transformer for underground services. Here is a link to the Manual for the Transformer
http://www.geindustrial.com/products/brochures/GEI-79025M.pdf. The switch is shown on Pp. 16 Figure 23. of the manual and is described as a Loop Switch with On-Off radial switch. The manual states, "The radial-feed, two position internalm oil switch is a gang-operated loadbreak switch. It is operated by a hot stick and uses manually charged overtoggle storage spring assembly that is independent of operator speed. The spring loaded operating mechanism ensures quick load breaking and load making operation. It can be used to de energize the transformer. The operatiing handle and name plate are located in the high voltage compartment. Load sheding was performed pior to de energizing this switch.
