奧地利 K&N（KRAUS & NAIMER）考爾斯和藍默爾集團在1907年成立于奧地利的維也納，公司創始人是法蘭茲·考爾斯和羅倫茲·藍默爾，其制造的產品被冠以著名的“藍系列”商標。 目前集團擁有六家工廠：奧地利K&N、美國K&N、德國K&N、新西蘭K&N、巴西K&N、愛爾蘭K&N。 轉換開關，接觸器和馬達啟動器的發展，是基于考爾斯和藍默爾在設計及生產電器開關超過七十五年的經驗，考爾斯和藍默爾率先引進這種凸輪操作開關，并逐漸被人們所認識，成為了世界上生產這類開關的先驅。 常見型號： CG4 CG4-1 CA10 CA10B CA11 CA11B CA20 CA20B CH10 CH20 CH11 C26 C32 C42 C43 C80 C125 C316 C315 L350 L351 L400 L600 L630 L631 L800 L1000 L1001 L1200 L1250 L1251 L1600 L2000 CAD11 CAD12 KG10B KG20B KG32B KG41B KG64B KG80 KG80C KG100 KG100C KG10A KG20A KG32A

提供凸輪開關和隔離開關與IDC和彈簧夾終端技術。在全球領導地位就是基于提供盡可能高的技術標準。諾希德優勢提供KRAUS&NAIMER全部產品，包括：主電源開關，維修開關，選擇開關，轉換開關，隔離開關，急停開關，按鈕指示燈附件等

KRAUS&NAIMER公司開創了許多新的發展。 二十年代末，就已經開始使用的新材料“電木”。 后來被稱為新的“電木開關”，并在業內所接受。早在1949年推出第一個模塊化設計的凸輪開關和技術革命性的開關，其特點影響所有后續的設計。 經過多年的發展已演變為凸輪開關的無可爭議的市場領導者，并建立了隔離開關的標準。基于多項專利，現有的產品線涵蓋全球市場，并提供技術上和經濟上的優化解決方案，解決每一個應用程序。

The C-Series switches represent the classic cam switch by Kraus & Naimer. With specific models for all current ratings they offer an ideal solution for a wide variety of applications. The CA-Series with fingerproof terminals from 10 A to 32 A is ideally suited for many standard applications where industrial controls, instrumentation and electric motors are involved. For low-voltage applications down to switching of electronic signals the CA4 and CA4-1 are offered. The CA4-1 has gold-plated contacts and guarantees reliable switching, even under adverse, aggressive environmental conditions. Fingerproof terminals, accessible either horizontally or vertically, captive plus-minus screws and integrated screwdriver guides designed for the use of motorized screwdrivers are some clear practical advantages of the CA-Series. Insulation stripping or preparation of the conductor is no longer required if switches of the CL-Series with Insulation Displacement Connection (IDC) are used. The time required for loosening the terminal screws, stripping, preparing of the conductors and tightening of the terminal screws again can be saved. The terminals of this switch series are stainless and acid resistant. The switches of the L-Series from 350 A to 2400 A are continuous current rated for off-load switching. They are designed for switching of resistive or low-inductive loads. The C-, CA-, CAD-series provide screwdriver access from the side. Basically the C-, CA-, CAD-series are designed for vertical wiring. Horizontal wiring is available for mountings E, EF, E22, FS., FT., VE, VE22, VF, VF22. See Mounting Diagrams for details.
