At the Bellville Technical High School we built these in Standard 8 (known as Grade 10 these days), which for me was in 1982. And no, I would not only have failed but probably whacked upside the arse if I bodged the power switch that badly. The original switch failed much later, and I replaced it with what I had.

We didn't know it at the time, but it's from the February 1977 Electronics Today International.

It does have some design faults.
