earlier this year I was building upgrades for my audio studio and was having trouble finding exactly the switches I wanted that were 1) the correct color 2) the right price 3) the correct throw. it seemed like every where I shopped I could easily find "normal open" switches but very few stores stocked the "normally closed" variety. and if they did it wasn't the switch I wanted to use or could afford.
I was about to make do but remembered the strange of eBay. for example if you need
bulk 20 sided dice you can find them bundled in a bag of 100. so I typed
DPDT normally closed which revealed
exactly what I was looking for. and for lots less.
example linkYMMV is the only cautionary thing I can say. shipping is often free. check to see where it's coming from if you are in a hurry as some of this is from Hong Kong. for my project I didn't care when it showed up.
