Kind of an odd source I'm referencing, but I'm looking for the identification of an electrical part in a video game item. Here are two pictures (screenshots of the 3d model), where I've circled the item in red...

Coil and mystery item, view 1

Coil and mystery item, view 2

The part actually looks really familiar to me, but I can't place what it is.

Keep in mind this is a virtual item in an artistically created computer game. But that said, I believe the artists may have referenced a real item, and I'm trying to figure out what it is.

My reason to identify it is because I'm building a prop reproduction of the item - the "Rail Gun" from the Metro 2033 game. I've got a build thread on the reproduction prop forum at http://www.therpf.com/f9/metro-2033-volt-driver-research-build-journal-167421/ if you're into that kind of thing :)

  • \$\begingroup\$ That was my first thought too, but unless they attached a fake wire to the top of the switch/pot, it's not one of those. \$\endgroup\$

Since it's part of a rail gun, it's very likely to be a Thyristor (Silicon Controlled Rectifier), though since there isn't an obvious gate connection, it could be a diode as well. I'm guessing the package is TO-48 or TO-65, but it's tough to be sure.
