I had occasion to dismantle a cheap pedestal fan the other day (Coles
Home Collection). It hadn't failed, but I wanted to see how it was wired
up (that's another story).

The cover to the button panel was held in place by four screws which
were identical except that two were philips head type, and the other two
had a triangular socket in the head.

I have bits to cope with most things I've encountered, but not those.
What's the point? Are they worried about competition for repairing these
$10 fans?

Do consumers regularly electrocute themselves by taking fans apart
without knowing what they're doing?
