Modular display cases and display system

A display system, comprising:

• at least two of the display cases, each display case comprising:
• a body having a first end and a second end;
• a cavity extending through the body from the first end to the second end, the cavity configured to receive at least one display item therein;
• a first end cap attached to the first end, the first end cap having an attachment device removably attachable to an attachment device of an adjoining display case;
• and
• a second end cap attached to the second end, the second end cap having an attachment device removably attachable to an attachment device of an adjoining display case, each attachment device of the first and second end caps configured to provide electrical continuity between metal tracks in each of the display cases;
• wherein one of the at least two display cases has a length different than a length of the other one of the at least two display cases, and wherein the at least two display cases are removably attached to each other such that the metal tracks of each of the at least two display cases are directly coupled to each other.

A display system, comprising:

• a plurality of display cases, each display case having an elongated body and a cavity extending through the elongated body, metal tracks extending through the cavity, and at least one attachment device on an end of the elongated body configured to attach to an adjoining display case;
• one of the plurality of display cases having a first length and one of the plurality of display cases having a second length different than the first length;
• and
• a switch system for electrically attaching the metal tracks to adjoining metal tracks, the switch system having a slidable switch operable to a first position and a second position, the first position for connecting a male member of the adjoining metal tracks and the second position for connecting a female member of different adjoining metal tracks, the slidable switch disposed below the metal tracks such that adjoining metal tracks and different adjoining metal tracks are electrically attached to the metal tracks in the display case via the slidable switch.
