Abstract

Abstract A two-piece spring latch assembly operable as a closure device for a load center cabinet, wherein the latch assembly is slidably engagable with the door of a load center cabinet. The latch assembly includes a sliding latch body having a top surface with a depression for facilitating engagement of the latch body. The latch body also includes a latch member for engaging the frame of the load center cabinet. A latch spring is mounted to the latch member and defines a spring member for urging the sliding latch body into a latched position. The latch spring also defines a latch bearing surface and a strike bearing surface. These surfaces are fabricated from the same material as the spring member and resist wear through repeated cycles of engagement and disengagement with the frame of the load center cabinet.
