Device for a busbar system, wherein a housing of the device comprises, on one housing side, electrical connection contacts which are configured in such a way that they are passable through feed-through openings of a contact protection baseplate module of the busbar system and are insertable into uniformly spaced contact openings located below the feed-through openings of busbar modules provided inside the baseplate module for producing a direct electrical and mechanical connection to the busbar modules.

An electronic breadboard system may include a computing device including a display screen. The display screen has a first portion to display an electronic circuit model and a second portion directly adjacent to the first portion. The electronic breadboard system also includes a translucent breadboard on the second portion of the display screen. The translucent breadboard includes a translucent face plate having a rectangular grid of openings exposing a plurality of contacts. The plurality of contacts are arranged lengthwise along each row of the rectangular grid of openings and orthogonal to a transparent back plate coupling the plurality of contacts to the translucent face plate. The electronic breadboard system includes a graphics controller. The graphics controller may illuminate a row opening and/or a column opening of the translucent breadboard to direct placement of electrical components of a computer model in response to user interaction with the electronic circuit model.
