Abstract
1,259,018. Heavy current switches. ALLMANNA SVENSKA ELEKTRISKA A.B. 14 May, 1969 [15 May, 1968], No. 24572/69. Heading H1N. A switch contact arrangement comprising a plug contact 1 and a cooperable sheath contact 2 with a plurality of contact fingers 3 pressed radially against the plug contact 1 (when the switch is closed), by leaf springs 5, is characterized by the leaf springs 5 being loosely inserted in longitudinal grooves 7 provided in the contact fingers 3 and/or the surrounding contact housing 4. The contact fingers 3 are made from extruded copper rods with shoes 8 of coppertungsten. The pressure point 10 of each spring 5 is positioned nearer the stationary contact member 9 than the shoe 8 to provide good contact between the base of the finger 3 and the member 9. The springs 5 are punched out of spring steel sheet. The surface of the finger 3 facing the plug 1 has several different radii of curvature to fit differing diameters of plugs 1, Fig. 3 (not shown). The contact housing 4 has an arcing ring 11 shaped to provide an annular groove 12 to help locate the fingers 3. The arrangement is used in low oil content switches.
