Abstract
A support structure for a circuit interrupter latch member includes a first side plate having a first opening, and a second side plate having a second opening. A first hardened bushing includes a first opening and a first perimeter. The first opening of the first hardened bushing is adapted to pivotally mount a first tab of the latch member. The first perimeter is coupled to the first side plate at the first opening thereof. A second hardened bushing includes a second opening and a second perimeter. The second opening of the second hardened bushing is adapted to pivotally mount a second tab of the latch member. The second perimeter is coupled to the second side plate at the second opening thereof. The hardened material of the first and second side plates is harder than the unhardened material of the first and second side plates.
