奥地利 K&N（KRAUS & NAIMER）考尔斯和蓝默尔集团在1907年成立于奥地利的维也纳，公司创始人是法兰兹·考尔斯和罗伦兹·蓝默尔，其制造的产品被冠以著名的“蓝系列”商标，提供凸轮开关和隔离开关与IDC和弹簧夹终端技术。

KRAUS & NAIMER公司开创了许多新的发展。 二十年代末，就已经开始使用的新材料“电木”。 后来被称为新的“电木开关”，并在业内所接受。KRAUS & NAIMER 早在1949年推出第一个模块化设计的凸轮开关和技术革命性的开关，其特点影响所有后续的设计。 经过多年的发展已演变为凸轮开关的无可争议的市场领导者，并建立了隔离开关的标准。基于多项专利，现有的产品线涵盖全球市场，并提供技术上和经济上的优化解决方案，解决每一个应用程序。

KRAUS & NAIMER目前集团拥有六家工厂：奥地利K&N、美国K&N、德国K&N、新西兰K&N、巴西K&N、爱尔兰K&N。 转换开关，接触器和马达启动器的发展，是基于考尔斯和蓝默尔(KRAUS & NAIMER)在设计及生产电器开关超过七十五年的经验，考尔斯和蓝默尔(KRAUS & NAIMER)率先引进这种凸轮操作开关，并逐渐被人们所认识，成为了世界上生产这类开关的先驱。
