What does a oil sending unit look like?

Most oil sending units have a wire or two coming out of the tip of them. They are very short with usually a wide base, like 22mm ish. Yet the compression threads that go into the block are small and fine. It's not going to look like much and would fit easily in the palm of your hand totally. Before I end, I just thought of a good description. It looks like a child's top or raddle.
