摘要

An improved locking member for the housing of an electric switching apparatus including a contact plate having a threaded aperture, and a screw-type electrical contact disposed in the aperture. The housing has an elongated slit disposed therein transverse to the direction of insertion of the contact plate into the housing which opens into the interior thereof adjacent the plate and the contact. The locking member is inserted through the slit into the housing for securing the contact plate therein. The improvement of the invention comprises the locking member comprising a planar sheet member having a recess disposed therein and a projection member integrally formed with the sheet member extending into the recess in the plane of the sheet member from one side thereof. The projection member is supported in the housing below the aperture in the contact plate so that it is engaged by the screw contact during insertion thereof into the contact plate and is bent downwardly from the plane of the sheet member below the housing slit. Withdrawal of the sheet member from the slit and the housing is thereby prevented.
