Hi Guys
Can some one have a look at
http://www.tini.org.uk/ha/B.bmp
This is what I believe the schematic to be of an electronic time switch.
It's about 1MB so appologies for the size. Component names arn't correct.
PADS 3&4 Supply power to the uP module that controls the switch, pad2
being the control line.
Pad 5 &6 are the AC supply, and pad 1 the switched AC output.
G1 being a backup battery.
Two questions, does this look reasonable, I've probably not got the
transistor right but as I can't ident it it's a guess.
Second, does taking pad 3 to ground cause the relay to switch.
Sorry for the questions but my electronis is about 12 year old and rather
rusty
Cheers
Stuart
