Please help explain this SPDT symbol
June 16, 2011
I had to kiss my ego goodbye before I posted this one. I can't believe I need to ask about an electrical symbol but... yeah.
Anyhow, I know what a SPDT symbol should resemble:
what I'm having problems with is this one:
The datasheet is succinct and I'm going with the educated guess that there are four legs for each switch (one switch = DIP4, four switches = DIP16). I can see that much in the symbol but what is going on with the connections? Where's the DT part of the thing? The SP part looks like the SPST diagram. Are there two legs connected to one of the throws maybe? Somebody here has to know for 100% certain.
