How do coin cell battery holders work?

Im working on a miniature that I want to put some lights in the base. Im using a plastic, frosted bottle top as the base (like the one on a gatorade bottle) - its about 1 3/4 inches/4.5 cm in diameter. In a perfect world, Id like to rig it ALL up in the bottle top - LED, Resistor, and a coin cell battery.

Ive seen the holders available, but I cant really see much from the pictures. Do they have metal pins that you just solder the wires to, just like a regular battery holder?

Is this even possible, or am I just trying to cram too much into a tiny space?

I've seen two types - one has surface mount pads on the sides/underside and the other has pins.

Here's an example with pins...

and with tabs

There's also a type that looks just like the pin version, but with contact tabs.

Awesome - thanks for the quick reply macfrank. Id had seen both of those types, but the pictures were low quality, and from the very top down. Those are perfect pictures, and exactly what I was looking for. Thank you!
