Hi guys,

This question is for anyone who's pretty good at electronics and circuitery.

You probably know there is a way to use regular ON/OFF toggle switch with a "hacked" keyboard controller, by building a small circuit with a relay and capacitor.
Only problem is, the cost can get pretty high when a lot of toggles are involved... relays sells for approximately 3-4$ each.

SOmeone in a foum on AVSIM mentioned it was possible to do the exact same thing using SCRs (thyristor) instead of relays. SCRs sells for approximately 0.75$ each.

So, could anyone confirm if this really can be done and if so, provide a basic circuit using SCR - and last but not least, what type of SCRs would be required, assuming the power source would be a 12v battery?

Thanks guys!


Here's the link I'm refering to above:

Yes, it's possible to do that. I don't think I'd use an scr. A better choice would be an opto-isolated FET.

If cost is an issue, the implication is that you need to connect a number of switches. If so, you may be better served by buying one keyboard emulator rather than building a number of individual switch buffers for a hacked keyboard.

Try this link out, it uses an non-relay system to incorporate toggles.
