There was a Leviton (well known brand) timer power switch that would prematurely fail. They spec’d out too low temperature rating of a capacitor that was right next to a heat source and cook itself to death: https://m.youtube.com/watch?time_continue=315&v=BQM4ERy-wpY https://m.youtube.com/watch?time_continue=315&v=BQM4ERy-wpY https://electronupdate.blogspot.com/2017/12/leviton-ltb30-buzzing-timer-failure.html?m=1 https://electronupdate.blogspot.com/2017/12/leviton-ltb30-bu... So yeah, tried too hard to save 2 cents

That's not a 'saving 2 cents problem', that's a failure to recognize the thermal environment and requirements for a component, which is kind of my entire point: engineering isn't easy.

  The 6 cent capacitor is more durable and can absorb an error like that without the product failing. Like they say that anyone can overbuild a bridge but only an engineer can make it barely stand up. A lot of that cost cutting is useful but it tends to go too far.

    >Like they say that anyone can overbuild a bridge but only an engineer can make it barely stand up The majority of biggest suspension bridges if I remember correctly are barely standing up. They use above 80% of the cables carrying capacity for themselves.

    Same point: anyone can build a submarine that gets to the Titanic.

      Yeah. Anyone can get to the bottom of the ocean. Getting back up alive involves more skill.
