Solid state relay wiring

[Buffalo Tom]

I have never used solid state relays or optocouplers so I'm not familiar with how they work but here is what I wanna do.

N.C. contact to turn on indicator A when control pin is 0V
N.0. contact to turn on indicator B when control pin is 5V
So it's a toggling function between A or B indicators running on 9V
Controlled with a single 5V control pin.

Is this correct wiring? Using Panasonic AQW610EH

Wiring is correct..

CLRs values might need a mindful estimation..

I don't understand these. How can they define one switch or the other as normally closed or normally open when they appear identical but separately controlled?

I very much doubt the little diagram is entirely accurate or tells the whole story. I smell an over-simplification!

From what I can see there are different devices (NC and NO) in the same package.  The datasheet makes a point of saying it.
The NO types are more common.   But there are NC types,

So are one set of switches enhancement mode and the other set depletion mode?

If there is a little linear region between fully open and fully closed,

Someone here will make a subverted fuzz out of it !

Yes, the NC types use depletion mode (plus an active pull-down to increased speed).

FWIW, I wasn't sure they worked that way until I read the PDF.

Some time back I played around with using MOSFETs for phasers and came up with linearized version of the back to back MOSFETs.   I used those back-to-back MOSFETs as switches in 1994.

It's probably a little messy to linearize those switches but not impossible.

Finally got the part today. The wiring works and the Panasonic chip acts like a SPDT switch as I hoped. I have 680Ω resistors to get 1,14V, 6mA. Im using the led pin on a AVR microprocessor I bought from Jack Orman for the 5V on/off.
