We have a B&D rice cooker that quit working. When you plug it in, the light
indicates 'warm' but the switch won't work when you depress it. I took the
bottom off but couldn't see anything that would lock when you hit the
switch. It is out of warranty, so the $64 dollar question is: can you
replace the switch or as is usual in cases like this, it's just cheaper and
easier to buy a new one.
