That's a nice looking switch. Wow. I bet it makes a nice thwack.
It looks like there are two ground/earth wires on one ground post and two hots on the corresponding hot. Two circuits are being powered through the one switch. Would need to see more of the device guts to understand why.
I think that would be classified as a Rocker switch with a Paddle actuator.
From the back it looks like a DPST switch.
Double/Dual Pole means it switches two separate pairs of conductors at once. Many circuits only need to switch the hot or the ground wire and use a Single Pole switch. A SPST switch has 2 terminals on the back. This one has 4 so it can switche both the hot and ground at the same time.
Single Throw means it's got only off and on. No other position. Dual Throw would have 3 positions, so a SPDT would have 3 terminals on the back, and a DPDT switch has 6 terminals on the back.

Any numbers or markings on the back? I wouldn't be surprised if this isn't available any more. To me it looks like something from the 1970s-1990s.
There might be markings on the circuit board that help date it.
It has very few markings on it, I did find "pronic" etched into some of the metal. It was many years ago I pried it out of the rest of the system so I can't give much info on it unfortunately. I got it from the power supply of the computer that housed the big hard drive from 1990 found here (I also no longer have this hard drive): https://lemmy.zip/post/42867255
I'm not home right now but when I'm back I can try to find more markings.
