Because of permanent improvement of our products, drawings, descriptions, features used on these data sheets are for guidance only and can be modified without prior advice only and can guidance for are sheets data used on these features descriptions, drawings, of our products, improvement of permanent Because The Reed switch invention in 1936 and its mass production in the 1960s enabled the miniaturization of level switches, which are now used in many electrical appliances applications. JPC level switches are constructed according to the technology of floats actuating an electrical contact. If the level changes, the movement of the float, which follows the variation of the position of the water surface, actuates an electrical contact. This contact is usually provided by a reed switch (Also known by the acronym ILS in French), but can also be a micro-switch.

  • Panasonic Switches
    GENERAL CATALOG SWITCHES Panasonic Switches Development cycles in modern industry are becoming ever shorter and more complex, and they require a high degree of engineering. Components integrated into machines must therefore not only meet the current qualitative and technical standards but must also fulfill functional and application demands. Individual products can often only be integrated after they have been customized. Panasonic Electric Works has always stood for product innovation – also when it comes to mechanical switches. Our immense portfolio includes switches in all common sizes and with various IP degrees of protection, and are guaranteed to cover all standard requirements. Our switches are characterized by a large switching capacity range, long lifetime and exceptional reliability. A wide selection of supplemental actuators coupled with various terminal styles, e.g. solder, quick connect, PC board terminal and cable connections, maximize flexibility and ease application design. In addition, we concentrate on the development and implementation of customer-specific solutions: Does the cable have to be a little bit longer? Or is a pluggable solution necessary? With the engineering know-how at our European manufacturing sites, we guarantee flexible, on-time delivery and provide immediate, on-site technical support.

While such pressures have no appreciable effect on silver- can result in contact problems and even early contact failure. cadmium contacts, they do result in increased material wear of fine silver contacts. Also, an interface voltage of several tenths of a volt can result For example, some contact materials require an arc to keep them free of with fine silver contacts because of the sulfide film. This film has been sulfidation, oxidation, and contaminates. Such materials on contacts known to capture and imbed airborne dirt. Breaking through this film used in a dry or low-level circuit can result in the contacts failing electrically generates electrical noise. Because of this, fine silver contacts are not to close the circuit, even though they make physically. The contacts may used for low-level switching, such as audio circuits. Rather, fine silver look clean, but this is deceiving. In reality, there is a very thin film of and silver alloy contacts are for use in circuits of 12 volts, 0.4 ampere, or insulating sulfidation, oxidation or contaminates on the surface of the more.

Contact Protection Requirements When switching inductive loads such as relays, solenoids and transformers, reed switch contacts require protection in order to ensure long, dependable life. When current is interrupted, the inductance or electrical inertia of the load generates a large high frequency voltage, which appears across the switch contacts. If the voltage is large enough, it can break down the medium in the gap between them, making a conductive path. This phenomenon, called “arcing,” is the spark you see. Arcing can cause the contacts to burn, weld together or stick; thus, giving unreliable performance. The purpose of protection circuits is to prevent arcing, by shorting this voltage through an alternate path. Recommended Protection D.C. A 1N4004 diode (or equivalent) connected cathode-to-positive, as shown in Figure 1, is recommended. The diode does not conduct when the load is energized, but conducts and shorts out the generated voltage when the switch opens. The generated voltage Figure 1 always acts in series with the applied voltage. $##ONTACT (DRAIN THE LOAD) Protection $RAINTHE,OAD A.C.
