Abstract: A quick change mounting plate for securing an end fed or a side fed electrical terminal applicator, alternatively, to a press for operating the applicator, is provided with latches for locking the base plate of the respective applicator to the mounting plate. Each latch is movable between a raised latching position and a lowered position in which the latch does not interrupt the surface of the mounting plate, upon which surface the respective base plate is to be supported. The latches, one of which is positioned substantially centrally of said surface, are located to engage, in their raised positions, the edes of the base plate of the respective applicator. The latches which are not to be used for this purpose in respect of a particular base plate are kept in their lowered positions so that surface to surface contact between such base plate and the mounting plate can be achieved.
