2-way Switch

[bhaazee]

I can understand the working mechanism of a 2-way or 3-way electrical switch. However, would like to know if a 2-way or 3-way switching mechanism is possible with a electronic circuit?

 

Also, if it possible with a combination of mechanical switch and electronic circuit (means one of the 2-way switch is a mechanical switch and other switch is an electronic circuit)

Sure, I can think of a bunch of ways off of the top of my head. I don't know if any of them are optimal.

One simple one is to just replace your switch with a pair of transistors. Have your logic circuit supply current to one of the other in the same way your physical switch would.

Relays also seem like the kind of thing that would be used in this application.

It's basically a mechanical switch driven by a small electromagnet.

 

If you put a tiny bit more thought into it, you could probably just build a series of and/or gates, too.

All depends on the application, really.

This means there are electronic switches available for multi-switching application like switches for staircase lights.

 

If possible, Could u plzz provide me a simple electronic circuit diagram for a 3 way electronic multi-switch

and btw thanx for the reply

The SCRS are much common in the use as they can effictively switch the circuit at high frequencies.And what you said above i dun get much but i think u wanna ckt that can switch on and off if some one comes yes thyristor can do that effectively
