Agricultural Machinery

Agricultural machinery operates in harsh environments with high vibration, dust, moisture and extended duty cycles. Battery switch relays are critical in these machines, managing high current loads for starting and powering auxili

The Problem

What Goes Wrong in This Application

Pain Points

  • Battery switch relays that fail due to arcing and contact welding under high current loads
  • Relays that degrade from vibration and dust ingress in unsealed or poorly shielded enclosures
  • Long lead times for replacement parts on older tractor and harvester models still in active use
  • Inconsistent part numbers across different manufacturers, making stock management difficult
  • Depots forced to hold multiple variants of the same relay type due to lack of cross-referencing

What Buyers Need

  • Relays that match the OEM part number and electrical specifications for direct replacement
  • High reliability under continuous high current switching in 12V and 24V systems
  • Consistent supply of the same part number to standardise inventory across a mixed fleet
  • Packaging suitable for storage in agricultural workshop warehouses, not retail displays
  • A warranty that covers parts stored in stock before installation
Where They Are Fitted

Typical Scenarios

  • Replacing battery switch relays on a fleet of older tractors still in daily operation
  • A repair shop sourcing a single relay for a harvester with no current OEM availability
  • A parts distributor building a stock list for agricultural vehicle maintenance
  • An OEM service provider requiring exact replacements for field service kits

Questions Buyers Ask

Questions From Agricultural Machinery Buyers

Can you supply battery switch relays for tractors and harvesters no longer in production?

Yes. Use the number from the original relay or send a photo of the unit. We match the voltage, pin count and current rating to confirm availability.

Do you supply relays for both 12V and 24V systems?

Yes. Our catalogue includes battery switch relays rated for both 12V and 24V, with current ratings up to 100A.

What is the minimum order quantity?

10 pcs per catalogue item. Small trial orders are accepted.

Can I get free samples?

Yes. Samples are free of charge. The buyer covers freight costs.

How are the relays tested before delivery?

Every relay undergoes 100% leakage test and performance parameter verification in our in-house laboratory. Production follows IATF 16949:2016 standards.

What warranty applies to parts stored in a workshop?

12 months from the B/L date. Stock held in storage is covered when it is fitted.

Can I order a mixed list of relays and switches?

Yes. We consolidate multiple part numbers into one shipment. Send the list of OEM numbers and we will quote as a single order.
