Bosch goes back to basics with essential relay know-how
More than 160 part numbers are available in the Bosch relay range.

Bosch has published an essential guide to relays in its latest newsletter.

Simply put, relays are electrical switches that use low current switching to activate high current components.

In it’s guide, Bosch say: “Before buying, selling or installing any type of relay, verify the correct application.

“Disconnect the power source of the vehicle, before carrying out the relay replacement.

“Verify that the connector terminals in the fuse holder or electrical compartment are free from corrosion.

“Ensure that the relay does not come in contact with water and oil, because it can affect the operation.”
