Abstract
Load break air switch incorporating quick make and break mechanical operator that includes arming and load release levers rotatable about separate parallel axes. A pair of compression springs are connected in uni-directional force transmitting relation between the arming and load release levers and are respectively disposed on opposite sides of the plane defined by the foregoing axes. Latching structure is provided to prevent rotation of the load release lever upon rotation of the arming lever until a predetermined amount of energy is stored in one of the compression springs. Improved pivot structure is provided for providing enhanced current transfer, the pivot incorporating a louvered contact band.
