Part of the issue is that the terminology of switches is confusing: on-off, on-mom, off-(on), etc. and some of it must be due to my last of skill in doing parametric searches on Digikey and Mouser. I just know the switch I am looking for is out there but which of the tens of thousands is it?<div><br></div><div>I have been using<a href="https://www.sparkfun.com/products/102"> this</a> Single Pole Double Throw (SPDT) power switch from Sparkfun. It works well but it takes up space and I only need a Single Pole Single Throw (SPST) variety. Ideally, I could find a push-on, push-off switch which - I believe - is written on-off in the switch function terminology but I have yet to find a source in my Google searching that would confirm this. </div><div><br></div><div>I found <a href="http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail&itemSeq=157282720&uq=635463031929636734">this switch</a> after a long search but I am still not sure it is the one I need as it only says it is on-off (and not the more descriptive push-on, push-off) anywhere on the documentation or website. Also, I am not sure if there is something else I am missing after Paul’s presentation where the switch had significant noise. This should not be a big deal for a power switch as I have a couple capacitors on both sides of the power regulator - correct?</div><div><br></div><div>I am sweating these decisions because I need to make a number of these boards for a project with the City of Raleigh and I don’t want to screw it up. If you have other suggestions within my component budget of $1.50 a piece, please let me know. </div><div><br></div><div>Thanks,</div><div><br></div><div>Chip</div><div><br></div><div><br></div><div><br></div><div><br></div></body></html>
