Song Chuan #85 Negative Relays with Diodes - 12V DC

These Song Chuan relays have an 85 negative polarity and allow a low current flow circuit to control a high current flow circuit. They are remote control electronic switches that are normally controlled by another switch, computer or control module. The internal diode within this relay protects sensitive equipment against voltage spikes. The lack of a mounting bracket on the relay allows an easy fit within standard fuse boxes. The best solution for full voltage applicable to head lamps, auxiliary lamps, fog horns, motors for fans, window lifters, air conditioners, heated rear windows, or the myriad of other equipment existing on vehicles today.


  • The diode eliminates voltage spikes which can damage sensitive electronic equipment.
  • Engineered to deliver a superior performance over a long life.
  • Diode polarity =Terminal #85 negative (-), Terminal #86 positive (+).
  • RoHS & ELV Compliant.
  • Part Number 74803 is a substitute for 73986.
