• HIGH SWITCHING CAPABILITY: 5-Pin SPDT (Single Pole Double Throw) 30/40 A Relay.
  • INTERLOCKING RELAY SOCKET: The relay socket harness base is interlocking designed for easy cable management and organization.
  • GREAT QUALITY: The durable relay and heavy duty relay socket with 5 wires are made by high-grade materials to ensure superior quality.
  • WIRE INSTRUCTION: Black - (85), Red - (87a), White - (86), Yellow - (87) and Blue - (30).
  • PACKAGE INCLUDE: 6 relays & 6 relay sockets with wires

Relays are great for helping prevent electrical fires and for distribution of power to low voltage lights. I'm no mechanic and have even less knowledge of vehicle electrics, but a quick Google search helped me in wiring this up correctly to my lights. 6 relays for under $15 is a phenomenal deal, and they're high quality. I still have 5 left, I guess I need more lights on my truck! 😂

Like that the sockets can be linked together. I needed a way to be able to switch a 30 amp load without having to get a heavy duty dedicated switch. I plan on building a trailer light test unit and using a rotary switch to switch between functions and only the trailer brake activation needed to be able to handle up to 30 amps. The relay will go between the rotary switch and the output to the brakes and the rotary switch will directly power the lights.

Use 4 of them to open and close a bus door. Little bulkier then the factory controller but not $180 and now more serviceable. My setup reverses polarity on one set of relays over the other. We also added a wireless kit at the same time.

You have to use these if you power up large accessories. If you power up anything bigger than 20 amps the switch will be come hot. This is much safer way to go.

Solid. Gave enough wire to make the project I was working on

These work well and easy to replace those more expensive ones which can be 12+ easily each. So these work great and are good quality for what I have seen so far.

Great value for 6 relays! I used for custom car wiring for horns, lighting, etc. Nice socket & color coded pigtails to make wiring simple.

They're somewhat bigger than I gathered from the photos, but this was not an issue. If you follow the diagram that comes with them, you should have no wiring issues. I used for a simple, low-amperage project on my car and they are great. Can't comment on how they hold up to higher power demand yet.

Works as advertised. Plug and play. Exactly what the pictures show and durable as well. Replaced all three on my craftsman lawn mower. No problems to speak of. Great price great product.

There is a story here. In summary : they work [b]fine[/b] when used within specification. The coil is black/white wires and 130 mA at 12 VDC. Yellow wire is the pole.
