Order relays and contactors at Bürklin Elektronik
For safe and reliable switching on, switching off and switching over of circuits, the integration and use of relays or contactors is recommended. An effective relay or contactor increases the service life of electronic devices and is easy to integrate into the circuit.
Furthermore, it increases the resistance to voltage and current peaks and enables potential-free isolation of the load circuit.
Bürklin Elektronik offers power-optimized relays and contactors for controlling switching tasks in its online store. Together with leading manufacturers, we provide a comprehensive range of electromechanical components for you.
Whether for control functions of industrial machines and systems or in the automation of buildings and in the automotive sector: In the store you are guaranteed to find the right item for your application - from PhotoMOS relays to solid-state relays to industrial relays.
