nr date March 2010 About the optical component the optoelectronic component Slotted opticalswitch In telecommunication , an opticalswitch is a switch that enables signals in optical fiber s or integrated optical circuit s IOCs to be selectively switched from one Telecommunication circuit circuit to another. The word is used on several levels. In commercial terms such as the telecom opticalswitch ... optic communications Switch, optical optics stub id Sakelar Optik he zh ..., independent of how the light itself is switched. Away from the world of telecom systems, an opticalswitch is the unit that actually switches light between fibers, and a photonic switch is one that does this by exploiting nonlinear material properties to steer light i.e., to switch wavelengths or signals within a given fiber . Hence a certain portion of the opticalswitch market is made up of photonic switches. These will contain within them an opticalswitch, which will, in a small number of cases, be a photonic switch. An opticalswitch may operate by mechanical means, such as physically shifting an optical fiber to drive one or more alternative fibers, or by electro optic effect s, magneto optic effect s, or other methods. Slow optical switches, such as those using moving fibers, may be used for alternate routing of an opticalswitch transmission telecommunications transmission path, such as routing around a Fault technology fault .

about the optoelectronic component the optical component Opticalswitch The slotted opticalswitch , sometimes known as opto switch or opticalswitch but not to be confused with the optical component, is a device comprising a photoemitter e.g. LED and a photodetector e.g. photodiode mounted in a single package so that the photoemitter normally illuminates the photodetector, but an opaque object can be inserted in a slot between them so as to break the beam. Associated Electronic circuit circuit ry is provided which changes state when the beam is interrupted. For example, the carriage of a computer printer may be fitted with a projection which interrupts the beam of a slotted switch when it reaches the end of its travel, causing circuitry to react appropriately. Another application of the slotted switch is in the type of Mechanical mouse computer mouse with a rotating ball. The ball measures distances moved by rotating orthogonal shafts which drive chopper wheels turning in the slots of slotted switches. ref http books.google.com books?id Qq0CVfcAktUC&pg PA132&dq mouse opto switch&hl en&ei V9uZTM DB42OjAeLo1w&sa X&oi book result&ct result&resnum 4&ved 0CDkQ6AEwAw v onepage&q mouse 20opto 20switch&f false 123 robotics experiments for the evil genius By Michael Predko, Myke Predko description of wheeled mouse operation ref This device uses the same basic components as an opto coupler , but is operated by manipulating the light path instead of the photoemitter input.

unreferenced date February 2008 In electronics , a crossover switch or matrix switch is a switch connecting multiple inputs to multiple outputs using complex array matrices designed to switch any one input path to any one or more output path s . There are blocking and non blocking types of cross over switches. These switches can be mechanical Microelectromechanical systems , electrical, or optical non linear optics , and are used in electronics and fiber optic circuits, as well as some optical computer s. A banyan switch is one type of cross over switch. Their complexity depends on the topology of the individual switches in a switch matrix how wide it is by how many plies or layers of switches it takes , to implement your desired crossover logic. Typical crossover matrices follow the formula an N N Banyan switch uses N 2 log N elements. Other formulas are used for differing number of cross over layers and scaling is possible, but becomes very large and complex with large N N arrays. Computer aided design CAD and Artificial intelligence AI can be used to take the drudgery out of these designs. The switches are measured by how many stages, and how many up down sorters and crosspoints. Switches often have buffers built in to speed up switching speeds. A typical switch may have a 2 2 and 4 4 down sorter, followed by an 8 8 up sorter, followed by a 2 2 crosspoint Banyan switch network, resulting in a 3 level sorting for a 3 stage banyan network switch.

Unreferenced stub auto yes date December 2009 A float switch is a device used to detect the level of liquid within a tank. The switch may be used in a pump , an indicator, an alarm, or other devices. Float switches range from small to large and may be as simple as a mercury switch inside a hinged float or as complex as a series of optical or Electrical conductivity conductance sensors producing discrete outputs as the liquid reaches many different levels within the tank. Perhaps the most common type of float switch is simply a float raising a rod that actuates a Micro switch microswitch . gallery caption Opened float switch from a sump pump widths 240 heights 180 File Float switch on.jpg float switch on File Float switch off.jpg float switch off gallery A very common application is in sump pump s and condensate pump s where the switch detects the rising level of liquid in the sump or tank and energizes an electrical pump which then pumps liquid out until the level of the liquid has been substantially reduced, at which point the pump is switched off again. Float switches are often adjustable and can include substantial hysteresis . That is, the switch s turn on point may be much higher than the shut off point. This minimizes the on off cycling of the associated pump. Some float switches contain a two stage switch. As liquid rises to the trigger point of the first stage, the associated pump is activated. If the liquid continues to rise perhaps because the pump has failed or its discharge is blocked , the second stage will be triggered. This stage may switch off the source of the liquid being pumped, trigger an alarm, or both.

Image Turingswitch.png right thumb 200px Turing switch The Turing switch is a logical construction similar to the Turing machine . The Turing switch models the operation of a basic network switch in a network of switches, much the same as a Turing machine models the operation of a basic computational entity. Both are named in honor of the English logician Alan Turing . Some introductory research on the Turing switch was started at the University of Cambridge by http www.cl.cam.ac.uk jac22 Jon Crowcroft . In essence, Crowcroft suggests that instead of using general purpose computers to do packet switching, the required operations should be reduced to application specific logic and then that application specific logic should be implemented using optical components. The work is not actually based on Turing s research. A Turing switch consists of a Switched fabric switching fabric , one or more ingress interfaces also referred to as sources , one or more egress interfaces sinks , and a decision procedure to determine an egress interface given an ingress interface. Interfaces are sometimes referred to as ports. A packet cell or switched unit arrives at an ingress interface, the appropriate egress interface is determined by the decision procedure, and the packet is then transported across the switching fabric to the egress interface. A packet is a symbol or sequence of 1 s and 0 s. An ingress interface is connected to an ingress line, an egress interface to an egress line. The ingress line is said to feed the ingress interface the egress interface feeds the egress line. ref Jon Crowcroft http www.cl.cam.ac.uk techreports UCAM CL TR 556.pdf Turing Switches.

A pull switch is a switch that is actuated by means of a Link chain chain or string. An electric pull switch is attached to a toggle type switch one pull to switch on and next pull to switch off. The most common use of a pull switch is to operate a ceiling electric light . The ceiling fan is another appliance often operated by pull switches. Pull switches may be either two position open or closed or multi position allowing for different fan speeds or levels of illumination . Mounted inside a pull switch, there could be two types of two position toggle switches. In both cases the stable physical open or closed situation would be switch in outer and string in upper position. One type would switch to closed alternatively open already during the initial pull in the string. The other type would switch to closed or open only when releasing after a full pull. With the first type, the weight of the string and handle could accidentally switch the load intermittently on and off, when still around the initial position depending on the internal spring . This could potentially increase the danger of overheating in the switch. In a damp environment, electrical pull switches have a safety advantage because the user is separated from the electricity by a significant distance and if the lead is made of an electrically insulating material, such as cotton string. citation needed date September 2008 Most commercially available pull switches use a short length of ball chain, which may then be connected to any number of optional leads for added length or decoration. Leads for decoration or utility are usually made of metal or plastic. They can come in many different shapes ranging from animals, geometric shapes, or look just like a weight.
