    摘要： The contact fingers (49) of electrical switching apparatus (1) have radial convex surfaces (107) centered on the pivot pins (51) which seat on concave surfaces (109) in the molded contact carrier (47) to transmit bending loads on the pin (51) into the carrier (47). A seal member (93) which snaps onto the end of the pivot pin (51) has fins (99) which extend between the contact fingers (49) to block flow of arcing gases through the carrier (47). For lower current ratings, some of the contact fingers (49) are replaced by annular spacers (119) which also transmit bending moments into the carrier (47) and restrict gas flow. A stop ledge (77) on the carrier (47) against which the contact springs (79) bias the contact fingers (49) has a recess (83) which allows the center fingers (49c) to project farther toward the stationary contacts (39, 57) so that the arc toes (55) on these fingers (49c) are the last to separate on opening and the arc is concentrated on them. The drive pin (129) connecting the carrier (47) to the operating mechanism has flats (137) which key it for engagement in a slot (135) in the carrier (47) for installation and removal only with the carrier pivots (73) lifted out of their bearing pockets (113) by removal of the rear casing (7).
