Hello, I'm on Mouser looking for a dpdt pushbutton for a project I'm working on. The terminologies they use to describe the switches and the statements on the datasheets are confusing me.
What I'm looking for exactly, as far as the throws, is non-latching, throw-1, which would be the non-compressed state of the button, should be normally-closed, and by compressing the button, I switch to the normally-open throw of the switch.
Can anybody further describe such a switch for me, or have any references? Thank you.

 

The "normally" applies to the non-compressed state.
Try DPDT, NC as parameters.

 

A DPDT momentary switch has two separate switches. Each has a common terminal, a normally open terminal and a normally closed terminal.

Do what I do, drop them an email with your requirements.

The problem is that RS, Farnell//CPC/Newark, Mouser, etc etc, all allow complete idiots to populate the data to their websites and these idiots all have different opinions of what search filters should apply to any given part.

I needed a low profile pin header the other day, couldn't find one due to the filters on those sites, searched Google and found one on a site i'd already searched, but it wasn't the exact spec I needed, so I stopped wasting my time, sent them an email and started wasting theirs instead.

Waste their time instead of your own and maybe one day they'll sort out their websites to actually work properly.

I've had awful luck with a variety of sites that I no longer frequent, but Mouser has always worked quite well for me. I'm surprised they made your list of bad sites. They're my #2 pick for parts shopping (DigiKey edges them out for #1 in my book.)

As for the TS's switch requirements, the only part I sometimes find difficult when shopping is the distinction between latching vs. momentary on states. It seems that different manufacturers notate things differently when you get into multi-throw switches, particularly ones which mix momentary and latching, like "on - off - mom." Still, you can get quite close with search filters and then just confirm your requirements in the datasheet.
