Abstract (en)
[origin: US5228559A] A section switch has a pivoting blade connected to a first connector. The blade is provided with a contact hammer for engaging contact jaws connected to a second connector. The section switch includes a first contact finger fixed to a first spring and electrically connected to the second connector. A second contact finger is fixed to a second spring. The fingers come successively into contact during an opening operation of the section switch with an arcing horn that extends the hammer. The second finger and second spring are disposed so that the opening movement of the section switch causes ever-increasing amounts of energy to be stored in the second spring to cause the finger to rapidly escape from the arcing horn after a given opening stroke. The hammer is rotated about its axis to reduce contact force between the hammer and the jaws during opening of the section switch.
