Just think about most door bell buttons, I guess... rampy |

Techinically, it is two SPST switches, as it can be wired either Normally open or normally closed, but not both ways together. The switch only activates one circuit (even though it could go to multiple inputs), and only has two positions. (Down or up), thus SPST. FWIW, SPDT, is a two position switch with a single circuit - ON-ON or ON-OFF-ON (they can be momentary or continuous). This circuit will turn Light A on from Power A in position 1 and Light B on from Power B in Position 2. DPST is a switch that turns Light A on from Power A and Light B on from Power B or both off. And a DPDT would turn A on from A and B on from B OR C on from C and D on from D. FWIW --- End quote --- Hehe. I was waiting for this one, and I actually had to think about it for a while before I posted that last tirade. And to be quite honest, I don't really know how they are "advertised" or spec'd. But electrically, there is no difference between a SPDT toggle and a NO/NC Momentary like we are talking about. If you hook X input to the NO and Y input to the NC, when you press the button, you get X and when you release it, you get Y. So there are indeed 2 throws, it's just that one is favored by the spring return :D BTW, to anyone who thinks this thread is "retarded", nobody is twisting your eyeballs to read it :). After you understand all the basics, there is nothing left to discuss but nuances and technicalities. Just because you don't find it interesting or informative, doesn't mean that someone else won't.

What the hey, lets start a flame war! Randy - bite my lily what irish arse Rampy - Star Trek is terrible, and yes.. your a geek Hoagie - there's no such thing as a bad question, and this stuff can be pretty confusing. I just finished my 1st cab myself and it took alot of research on here. My post wasn't intended as a slight to you or your question at all. |

What do you expect with a community that is more than likely to consist of "geeks... As long as no one brings up Natalie Portman, or ask which Star Trek series/cast was best we'll be able to maintain status quo around here. Rampy --- End quote --- I'm not a Star Trek fan, but that Natalie Portman sure melts my butter! ;) |
