KRAUS NAIMER conversion switch

The Kauls and Lemmer Group was founded in Vienna, Austria in 1907 by Franz Kauls and Lorenz Lemmer,It is a low-voltage switch that switches multiple circuits. Multiple moving contacts are stacked and welded on the shaft, and when the shaft rotates, the moving contacts are sequentially connected or disconnected from the stationary contacts to switch the circuit. Electrical appliances that switch circuits from one set of connections to another.

There are two types: discrete and integrated Also known as a combination switch, it operates differently from a knife switch as it is a planar operation that rotates left and right. It has the advantages of multiple contacts, multiple positions, small size, reliable performance, easy operation, and flexible installation. It is commonly used as a power supply introduction switch in the electrical control circuit of machine tools, playing a role in isolating the power supply. It can also be used as a control switch to directly control the infrequent start and stop of small capacity asynchronous motors. There are also unipolar, bipolar, and tri polar. It is a switching device that can be used for converting two or more power sources or loads.

Composed of multiple contacts, it is commonly used in electrical equipment for non frequent circuit connection and disconnection, power and load connection, measurement of three-phase voltage, and control of forward and reverse rotation and star delta starting of small capacity asynchronous motors. These components are fastened together as a whole with bolts.

The contact system consists of several static contact seats embedded in an insulating shell and moving contacts in a movable bracket. The moving contact is a double break docking type contact bridge, which rotates to different positions along with the shaft attached with a handle to connect or disconnect the circuit. The positioning mechanism adopts a roller card ratchet structure, equipped with different limit pieces, which can obtain switches of different gears. Assembled from multiple layers of insulating shells, it can be arranged in three dimensions, reducing installation area, with a simple and compact structure, and safe and reliable operation. Switches with different connection methods can be formed according to the requirements of the circuit to meet the needs of different circuits.

In control and measurement systems, circuit conversion is used. For example, the switching of power supply for electrical equipment, the forward and reverse switching of electric motors, and the switching of voltage and current in measurement circuits. Replacing the knife switch not only simplifies the control or measurement circuit, but also avoids operational errors and reduces the number of components used.
