Hi all, I'm using an Omron G3MB-202P solid state relay, 5V flavor.  It's
a phototriac.  It's not behaving how I would expect though, hopefully
someone can clear this up..

Pin definitions:

1 - load
2 - load
3 - (+) input
4 - (-) input

Here's what I am seeing:

Connections:  to test this I just want to light an LED...

5V to Anode of 5V LED
pin 1 - cathode of LED
pin 2 - ground
pin 3 - ground
pin 4 - ground

This is how I start it up.

Now when I apply power to this, of course nothing happens as I expect.
I then switch over the pin 3 to +5V, the LED lights, as expected, I then
switch the pin 3 back to ground, the led stays lit.  In fact, no
arrangement of the input pins (3,4) will make the damn LED shut off, I
can't break the circuit once it's made...  Doesn't sound too useful of a
relay!

Hopefully I'm doing something obviously wrong!!

I've tried this with 3 different relays so I doubt they are defective...

Someone please smack me and tell me the simple solution! :)

Thanks all!
