FIG. 1 is a top plan view of a switch box for two pairs of stereo system
speakers of a preferred embodiment of the invention;
FIG. 2 is a front elevation view of the switch box shown in FIG. 1; and,
FIG. 3 is a right side elevation view of the switch box for two pairs of
stereo system speakers shown in FIGS. 1 and 2.
The left side elevation view is a substantial mirror image of the right
side elevation view and has, therefore, not been provided. The bottom and
rear sides of the switch box for two pair of stereo system speakers are
substantially unadorned and views thereof have, therefore, not been
provided.
