Hochstrora Umpo.l switch

The present invention "relates to a high-current reversing switch for low and direct voltage, as he a.B. can be used in the electroplating industry.

Such switches, with which currents from 1000 "to au several thousand amperes are switched, are extraordinary bulky and contain considerable amounts of copper, because of the conductor cross-section and thus also the cross-section of the switch parts the current strength must be correspondingly large »Now that so far so-called knife switch" or, segment after-switch Found use, the cost of materials is particularly large. This also has a very disadvantageous effect when switch

parts replaced due to wear and tear - "- weräeii have to ₉ because these

Parts large and are heavy and baw in the segment. "Scissor switches depending Schaltsrtyp quite Various» © dimensions have, depending on current Stärk determined that for-© eggs switches _etc. is holding "So you either need an extensive stock of Schalterersatsbestandteilen ^ what x # egen the large quantities of copper = expensive and bulky _p or you have to reckon with considerable delivery times.

_{y The} task of the invention was a toggle switch

This goal is achieved by the "Hpchstrom" according to the invention. Polarity reversal switch for Iied @ r ~ and direct voltage - which is characterized by "... ₉ that it arranges on a frame a carrier that can be displaced along a" straight line "with four contact bridges attached to it that are isolated from one another in relation to the named line and on both sides this' .üheägers.-awisqhen · end en

If _{contact bridges are used 9} which consist of several contact elements 9 which in turn have several contact pairs, one must of course ensure that every single contact of every contact pair and thus every contact element of the bridge closes cleanly _? Or in other words that the individual ... contact pairs independently beweglieh within certain limits Bind, - 'wherein -aur achieve the required contact pressure, the individual contact pairs should be independent sprung _e If .- .. may precipitate a pair of contacts for some reason, "as would, in such a way the closure of the other contact ©: not influenced =. flows «, '.".
