Yorx clock radio with 8-track

[Adam]

So I got another one of these digital clock radios. The good news is that the clock, radio and 8-track all work. The bad news is the radio won't turn off. I can switch from the AM/FM/FM stereo to the 8-track, but it won't turn off.

Assuming the problem was just the on/off button, I took the switch apart (and broke it in the process). But I figured since it was apart and I could see what connections the switch made when it was off, I could just duplicate those connections with clip leads, and the radio would be off. But no, it's still on.

So now I need to find a replacement for the switch I broke (in the 2nd pic). And it would be so much easier to sort this out with a schematic, but it's not even listed in my sams index (Yorx R5260). Where else could I look?
