Abstract
A mechanical interlock arrangement is disclosed for preventing misinstallation of a plurality of associated PC boards in the mainframe chassis of an electrical or electronic apparatus. Each PC board is mounted to a subpanel which has a mounting flange with a uniquely located key tab. This keying tab is accommodated within a selectively located slot on a member positioned traverse the front face of the mainframe chassis. The keying tab may be located along the top or bottom of the mounting flange and is made of substantially rigid material to prevent such protective keying function from being easily defeated.
