It looks reasonably similar to a high current momentary button I used to have for operating a set of musical air horns, rubber cover and all. I think it was rated for 20 amps but it didn't work by a clicking movement - it had an insulating board that held the contacts apart, and when the button was pushed a rivet through the insulating board moved down to make a connection across the contacts. With the same sort of terminals, you don't have a light duty switch, even if the switching action is different.
