	Cold Contact (other) Cold contact may refer to: * Cold contact (marketing), a sales strategy also known as cold calling * Cold contact (switch), a particular switch or relay contact * Cold contact (soldering), a cold soldering joint See also * Cold junction (other) Cold fusion (other) Cold joint Dry contact Dry contact may mean any of the following in electronics: ''No current'': A dry contact is the synonym of volt free — it is not "wetted" by a voltage source. Dry contact can refer to a secondary set of contacts of a relay circuit which does n ... {{disamb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Cold Contact (marketing) Cold calling is the solicitation of business from potential customers who have had no prior contact with the salesperson conducting the call. It is an attempt to convince potential customers to purchase either the salesperson's product or service. Generally, it is referred as an over-the-phone process, making it a source of telemarketing, but can also be done in-person by door-to-door salespeople. Though cold calling can be used as a legitimate business tool, scammers can use cold calling as well. Evolution Cold calling has developed from a form of giving sales pitch using a script into a targeted communication tool. Salespeople call from a list of potential customers that fit certain parameters built to help increase the likelihood of a sale. This modern cold calling, sometimes called "warm calling", tries to "dig deeply to understand" the potential customer. Criticisms With the development of newer technology and the Internet, cold calling has gained some criticism. Jef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Cold Contact (switch) In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type of switch is an electromechanical device consisting of one or more sets of movable electrical contacts connected to external circuits. When a pair of contacts is touching current can pass between them, while when the contacts are separated no current can flow. Switches are made in many different configurations; they may have multiple sets of contacts controlled by the same knob or actuator, and the contacts may operate simultaneously, sequentially, or alternately. A switch may be operated manually, for example, a light switch or a keyboard button, or may function as a sensing element to sense the position of a machine part, liquid level, pressure, or temperature, such as a thermostat. Many specialized forms exist, such as the toggle swi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Cold Contact (soldering) Soldering (; ) is a process in which two or more items are joined by melting and putting a filler metal ( solder) into the joint, the filler metal having a lower melting point than the adjoining metal. Unlike welding, soldering does not involve melting the work pieces. In brazing, the work piece metal also does not melt, but the filler metal is one that melts at a higher temperature than in soldering. In the past, nearly all solders contained lead, but environmental and health concerns have increasingly dictated use of lead-free alloys for electronics and plumbing purposes. Origins There is evidence that soldering was employed as early as 5,000 years ago in Mesopotamia. Soldering and brazing are thought to have originated very early in the history of metal-working, probably before 4000 BC. Sumerian swords from were assembled using hard soldering. Soldering was historically used to make jewelry, cookware and cooking tools, assembling stained glass, as well as other uses ...

	Cold Fusion (other) Cold fusion is a hypothesized type of nuclear reaction that would occur at or near room temperature. Cold fusion may also refer to: In science Muon-catalyzed fusion, before Fleischmann and Pons, was sometimes called ''cold fusion'' Pyroelectric fusion, first achieved in 2005, uses a pyroelectric crystal to accelerate ions to fusion energies with room temperature equipment Polywell fusion, uses inertial electrostatic confinement to attract and confine ions so densely that they fuse Nuclear fusion where the product nuclei have a relatively low excitation energy of around 10 to 20 MeV (this meaning is used mostly in the field of the synthesis of superheavy elements) In culture * ''Cold Fusion'' (novel), 1996 novel by Lance Parkin, based on the sci-fi TV series ''Doctor Who'' * "Cold Fusion" (''The Twilight Zone''), an episode of the 2002 TV series * ''Cold Fusion'' (2001 film), a documentary film about skiing and snowboarding by Warren Miller * ''Cold Fusion'' (2 ...
