Customer Reviews for VIAIR 40 Amp Relay

Great replacement, half the price of 1 at automotive store

Working great! Used it to control fresh water intake to a macurator on a house boat.

I needed a low voltage relay to interface my new doorbell camera with my intercom-centric electronic door chime. I chose this because it was the right voltage, had spade lug connections and had the ability to be screwed down to a backing board. It lived up to that, but buzzes unbelievably loudly when energized -- loudly enough to be heard throughout the house, rendering the doorbell moot!

I needed a low-voltage relay to use a doorbell camera with my electronic doorbell, and this one was the appropriate voltage, had a mounting hole, and would accept standard slide-on connectors. Perfect, it, seemed, and while it functions OK, it buzzes loudly while energized -- loudly enough that it can be heard throughout my house! Perhaps that raspy buzz would work in lieu of a doorbell, but it's not quite what I had in mind

It was the exact part I needed and got my light bar up and running.

I used these in an automotive application and they worked great. They have not been in use very long but the quailty seems good.

Just what I needed at a good price and fast shipment

Great price. Arrived sooner than expected(store orders fro HD usually do).

This is a product with a solid build and met all of my expectations.

Everything was excellent thanks

Perfect for the auxiliary backup lights on my 2001 ram pickup

It works perfectly for my aftermarket car horn. I've held it down for about 5 seconds straight, and it hasn't burnt up or blown up like the last one (from Harbor Freight).

Turning on and off like its supposed to. Not sure else to say

Came as described at a much cheaper cost than from auto parts stores

It was worth what I paid for it. I keep saying that but Home Depot keeps asking for my review on it. Do they do that with every product that they sell. Does anyone ever read these ?

Great product and great price. I use it for my 12V solar water pump, which only pulls 15 amps. So it can be used for things other than as advertised. It's only been in operation about a week. I just hope in a year I'm still raving about it and it hasn't died, like some cheap electrical components do. The wiring diagram is printed right on it - nice touch!
