ABSTRACT:
A latch/switch mechanism is attached to and operative for inserting and securing circuit modules into a housing while at the same time creating differing electrical connections during the insertion process. The latch/switch mechanism includes a latch lever with a cam and also included means to engage a support housing such as a notch or clip in the lever. The cam portion sequentially engages a plurality of conductive leaf springs and as the lever is rotated, the cam forces the making and breaking of certain connections of the conductive leaf springs to effect the various desired circuit connections and disconnections.
