I needed a relay with a normally closed (NC) connections and this has it. My application draws milliamps which was a concern because this relay is rated at 40A. Works fine. Even though I install this in a car, I can test this on my workbench with a 9 volt battery. I have tried small non-automotive relays, but they cost more, not as durable and do not have a mounting tab.

This is a nice, high-quality relay. It works well for automotive purposes, as well as many other applications. A few notes about it:
- The relay coil is 90 ohms, so when energized by its rated voltage of 12V, it consumes about 125mA, and when energized by 13.8V (as is typical in a car), it consumes 140mA. I was originally hoping to use this relay for a small, battery-powered application, but once I realized how much current the relay's coil consumes, I decided to use a different relay instead.
- It is physically fairly large (about 1" cube) and heavy, so again not good for small, battery-powered applications.
- It can be used in either a normally-closed (NC) or normally-open (NO) configuration. The pin configuration is shown on the top of the relay, which you can kinda see in the product's photo.
- It is physically fairly large (about 1" cube) and heavy, so again not good for small, battery-powered applications.
- It can be used in either a normally-closed (NC) or normally-open (NO) configuration. The pin configuration is shown on the top of the relay, which you can kinda see in the product's photo.
I would definitely recommend this relay, as long as the coil current is acceptable for your application.

This relay exactly replaces all 24 of the relays used in the electrical system of the 1988 Rolls Royce. The only drawback to an exact fit is the mounting tab. It does not pose a problem, but is not needed. Price compared to the Rolls price is great, less than 10% of the delar price.

I have been using this type of automotive relay for about three years to remotely control the AC line power to my laser printer. These relays have been completely reliable for this application and have handled the 10 - 12A startup fuser current without any problems whatsoever.
I use cheap 12Vdc wall wart style power supplies to supply the coil current. An inexpensive X10 type remote appliance controller is used to turn the 12 vdc power supply and attached relay on and off.
The whole thing is mounted in a cheap NEMA plastic electrical box. These boxes are available at any good hardware store. This cheap solution has been worry free.

Went to purchase a Meyer plow Module priced out of this world. Redesign with this relay - 4 on right side and 4 on left side using truck swiches to switch head lights back and fourth. The plow lights Halogen high amp vs truck circuit. Designed Halogen lights to work off truck solenoid. Newer truck circuits are not designed to work with high amp halogen lights and neither is the meyer modules. This 30-40amp relay work great and will last life-time for 1/3 of the price.

I'm making my ATV street legal for the US Forest Service. The after market cluster switch for turn signals, horn, & brake also has a kill switch. Since this particular ATV has an off switch that opens the circuit rather than shorts the circuit I looked for and found this relay with normally open and normally closed contacts. The NC will power the ATV until the kill sw is activated appllying power to the relay and opening the contacts thus removing power. Just the right current capacity.

Used them for the trim function in my boat, my Jeep fog-lights, Jeeps fuel pump, other vehicles, security systems. I keep spares just like fuses in my vehicles. Work fine and never have had any problems yet. Great product. Much cheaper and better quality the the local auto parts stores. I gave it a 4.5 only because its not waterproof.

Nice product, not watertight, but appear to be drip-proof and neither are the sockets that accommodate them anyways. These aren't the finest relays I've used but they are certainly a good relay for the price. I've installed many for vehicles all across the USA and Canada and have never had a customer report any failures with them.

I was very happy to locate this item. I used to buy these from Radio Shack BUT it seems that they (Radio Shack) are only interested in selling cell phones etc. now. I found these and will for sure buy more of them for my countless projects. this is in my opinion a very high quality product and it solved my electrical issue.

I searched a lot of websites for this product finding it at several. The price at Parts Express was by far the best. Some places wanted up to 5 times the amount for the exact same part. Shipping was great as my order was well packaged and the shipping cost was very reasonable. Communication was excellent and on target.

After searching local stores and the internet for automotive relays I purchased 10 of these Bosch type relays. For the price of 2 relays in the store I got 10 relays and harnesses. They perform as advertised and are well worth the money. Be sure to request or download the free relay wiring diagram from Parts-Express!

I bought these relays to modify the way my turn signal and running lights funtioned on my Pontiac Solstice. The relays work as advertised, are well marked with respect to the five pins/plugs on the relay (making it easy to connect it properly), seem to be constructed of good quality plastic, and are well put together.

I bought this relay for a marine application. I have a boat that uses these for the outboard trim. There are two, one for moving up and one for moving down. This relay on the volvo website was $59. This was such a big savings I bought two spares.

These items used to be at Radio Shack but now all they sell is cell phones and NOT items that repair techs like me need. I have used these relays to control electric fuel pumps all the way to lighting issues and am VERY happy with the quality.

these deliver what they promis, at a tremendus discount over what you may find at some shack-like transmitting stores, and they easily handle what they promise, as i have this one switching the power at the key for the starter on a car.

These relays aren't quite as nice as the Bosch relays. They aren't really sealed and the covers will pop off fairly easily. Other then that, they do a great job and are much less then the "actual" Bosch relays.
