I think this is a SCR, due to the circuit it is in..
Can any point me to a data sheet telling me what this is?
This is small circuit that is part of a water pump system. There
are only 3 heavy snap in contacts where #1 and #3 passes the AC
current through 2 turns of wire around a Reed switch envelope.
Another spade connection made from the start circuit that passes
through a SAC722, which looks to be a SCR, of the Gate and cathode,
through a 1k R and then through the reed switch, which then hits the
gate of the other assumed scr. On the other SCR, the cathode passes
through another coil that is wrapped around on just one end, not the
middle, like the first one, and then goes back out to #2 terminal where
it holds the circuit in the run position..
It looks like if you short #2 lug, which will create much more
current, the secondary coil will generate enough flux to work against
the main coil so that the reed switch will open and thus unlatch
this mess.
If need be I can create a ASCII schematic of it, if any one is
interested?
The strange thing about this is, I am having a hard time getting my
head around this because the anodes of assumed (SCRs) are both joined
together and go no where? That is like putting 2 diodes back to back.
So, if any one has a data sheet site for the "SAC722" or, just confirm
my suspicions of it being so, It would be much appreciated. Thanks.
