A configurable electrical circuit element housing used as a building block in prototyping and demonstrating electric circuits. A label (10) with a circuit element graphic (11) attaches on an electrically insulated housing top (20). Underneath is an alternating arrangement of electrically insulated connector guide walls (22) and guide posts (21) forming a square-like perimeter surrounding a circuit element (40). Circuit element leads (41) attach to bent coil connector binding posts (31) inside the housing. The bent coil connector binding posts, on sides for which they are installed, are the ends of bent coil connectors (30). The bent coil connectors bend around the guide posts forming arcs external to the square-like perimeter. The guide walls help form the arcs by pinching the bent coil connectors. The arcs of the bent coil connectors are resilient connectors which interface with similar connectors forming a bent coil connector coupling (50) interweaving their coil loops.
