In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
Dual ignition provides two advantages: redundancy in the event of in-flight failure of one ignition system; and more efficient burning of the fuel-air mixture within the combustion chamber. [ 1 ] [ 2 ] In aircraft and gasoline-powered fire fighting equipment, redundancy is the prime consideration, but in other vehicles the main targets are ...

The smaller cross sections are made of 19 strands, whereas the bigger has 37 strands. Two standard configurations for main lines consist of two contact wires of 100 mm 2 and one or two catenary wires of 120 mm 2, totaling 320 or 440 mm 2. Only one contact wire is often used for side tracks. [4]
Since a manufacturer could produce a conventional two-cylinder engine at similar cost to a split-single engine, a two-cylinder engine is usually a more space- and cost-effective design. [2] Most split-single engines used a single combustion chamber (i.e. two cylinders), however some engines used two combustion chambers (i.e. four cylinders) or ...
Stranded 22AWG jump wires with solid tips. A jump wire (also known as jumper, jumper wire, DuPont wire) is an electrical wire, or group of them in a cable, with a connector or pin at each end (or sometimes without them – simply "tinned"), which is normally used to interconnect the components of a breadboard or other prototype or test circuit, internally or with other equipment or components ...

Flatpack was one of the earliest surface-mounted packages. Small-outline integrated circuit (SOIC): dual-in-line, 8 or more pins, gull-wing lead form, pin spacing 1.27 mm. Small-outline package, J-leaded (SOJ): The same as SOIC except J-leaded. [80] Thin small-outline package (TSOP): thinner than SOIC with smaller pin spacing of 0.5 mm.
