English: "California" 3-way switch. Alternative to the conventional connection for a three-way switch. The lamp shell is never connected to the live terminal. A second lamp can be connected at A to light the end of a long corridor or as a pilot lamp to indicate the light in an outbuilding is left on.
For multi-way partitioning, when c=ceiling(n/k) and each of the k subsets must contain either ceiling(n/k) or floor(n/k) items, the approximation ratio of BLDM for the minimum largest sum is exactly 4/3 for c=3, 19/12 for c=4, 103/60 for c=5, 643/360 for c=6, and 4603/2520 for c=7. The ratios were found by solving a mixed integer linear program.
Enclosure comparison with normal wiring & with busbar system. Electrical busbar systems [1] (sometimes simply referred to as busbar systems) are a modular approach to electrical wiring, where instead of a standard cable wiring to every single electrical device, the electrical devices are mounted onto an adapter which is directly fitted to a current carrying busbar.

Circuit diagram of a 3-way switch and socket. The switch used to control a 3-way lamp is usually a rotary switch or a pull-chain switch. Although it is referred to as a 3-way switch, it has four positions, off, lamp one (low), lamp two (medium), and lamps one and two (high).
