With respect to the Def Leppard tune, what does "Switch 625" mean?

Joe Elliott said it was a tribute.

Def Leppard Switch 625

Switch 625

Although some sources say it refers to the date (June 25th? June 2nd 1975?) when Steve Clark (who wrote the song) lost his virginity, the truth is that the title does not have a deeper meaning. While designing the sleeve for "High 'N' Dry", the songs weren't finished yet. So, instead of putting existing song titles on the back, fake titles were written down, including the running times of the songs. One of those (imaginary) titles was "Switch", lasting 6 minutes and 25 seconds. The band liked the way it looked on the sleeve: "Switch (6:25)". Since they didn't have a title for an instrumental song that Steve wrote, they used this title for it, including the numbers that represented the length.

That's a good question!

it seems to have something to do with flyforward converters and extending their operating range ....thats all I could find
