Kraus & Naimer auxiliary contacts operate in conjunction with the main contacts of the switches and enable additional switching functions by providing feedback on the switching position. Depending on the switch position, they deliver status feedback, allowing for precise and reliable control of systems. We offer auxiliary contacts with various performance characteristics to suit your specific application requirements. Our auxiliary contacts are suitable for both alternating current (AC) and direct current (DC) applications.

Auxiliary contacts  

Auxiliary contacts can be used as normally closed (NC) or normally open (NO) contacts.  

Auxiliary contacts can be configured as normally closed (NC) or normally open (NO), enabling flexible adaptation to a wide range of control requirements. 

Depending on the product, we offer auxiliary contacts for low-voltage control signals as well as for higher voltages and robust control circuits. 

These features make them a key component in a wide range of industrial applications. For example, they can be used to monitor safety circuits and to control signal lamps, frequency converters, inverters, PLC inputs, and UPS systems.

Regardless of the selected mounting option of the switch, suitable auxiliary contact blocks can be configured for your application. In addition to factory-installed auxiliary contacts, most of our main switches can also be retrofitted with auxiliary contacts by the customer. 

Please contact our sales team to find out whether retrofitting is possible for your specific switch type.
