I'm trying to find a low cost Ethernet relay. At least that's what I think that it's called. I want to be able to control the relay over the Internet via a web browser. Ideally, it should have momentary contact closure as opposed to the on/off operation of a typical relay.

In searching for one of these devices, I've found quite a few, but at a cost of $200 to $400. Far too costly for my needs. Something in the $30 range would be ideal.

Does anyone here know of a device like this? Are there any better search terms that I should be using? A kit would also be okay, but it would be nice to have something that just works right out of the box.

Thanks in advance to those who reply.

Well, you could search for USB relay controllers like here https://denkovi.com/product.php?ProductID=44&gclid=CKS8zduI_LMCFQJx4AodgEUAzw

But the better way would be to look into a Raspberry Pi. It has fewer parts count as you'd just need the Pi, and a GPIO adapter.

Sounds like he is looking for an IP relay board that connects directly to the ethernet. Check the next page. I know $86 is not $30 but it's not $200-400 either.
