Relays are used to control electrical loads and are components of vehicle ECUs.
A relay is a remote-controlled switch powered by electric current to switch circuits on, off or over.


  • Relays

HELLA offers a wide range of relays for different applications. The electro-mechanical plug-in-relay has been one of HELLA’s core products for many years. As switch amplifiers used to control electrical loads in plug-in standard models, these electronic components can be controlled by control units. HELLA relays feature diodes or resistors to suppress interrupting voltage peaks in the relay coils and thus prevent interference voltage.

To ensure a maximum relay lifetime, the contact material is selected in line with the most demanding quality requirements.
