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.

A transformer includes a preformed winding with each turn having a channel cross section. The individual units are joined to form the desired multiturn winding. Another winding is inserted within the channel cross section of the multiturn winding. In one embodiment, the channels of the two turns are joined to form a closed passageway. In another embodiment, they are nested one within each other to form a concurrent passageway.
