Oops. I misread the requirement. I'd read his need as being for a normally 'off' switch that was sprung against the 'on' position. In re-reading the requirement, I think now that he means a sprung on-off-on switch. But I might be totally confused by now. 

Woody;

If you really want spring to off from either end of throw, try a relay triggered by the switch using an on-off-on switch.

He's an example of the switch, and since it's low power, the relay you choose can carry the amps.

Otherwise, Digikey has many offerings in on-off-on but none of them for off-on-off.

Minitronics has a toggel switch that dose this. I have used dozens of them. They are ON-OFF-ON and no matter if you throw them left or right they return to the center position, or off automaticly.

Very good, dependable switch with a 5 amp rating at a 120V.

What you are looking for are the MOM switches, miniature. (Momentary-Off-Momentary)

 

Have fun!

Hi John, I know what you mean, but I never made a smart mistake in my life and I have made a few, all dumb.

What does bother me is when someone post a question and people go through the trouble of offering advice, or information as best we can and they go away with out a thank you.

Even a statement as to what a bunch of nitwits we are and our advice is about as useful as water in a fuel tank would be better then being ignorned.

Woody, Radio Shack has exactly what you're looking for...

Hi Greg, great switch, it will be especially useful should one need to reverse AC motors. But that unit is center off position. As far as I know a center off-on-off switch is about good for nothing. I think woody is looking for a MOM configuartion or a simple on/off switch.

But like I said above, it does not matter for we may never know.

 

In any case thanks for the link, that's a switch I never knew the Shak had, good info.

I have used a SP switch normally off. On when pushed either way so you have two momentary on switches. I used them to control the individual functions of an operaring track. Real Trax operating track switches break easy so I used these. I got them at a local electronics store. Worked very well and no worry about leaving on and overheating the operating track.

Hi Ralph...I am not familiar with the GG switches, I do not have any.  I'm sure it could be worked out. I said I used a SP switch but now that I think of it, it may have been a DP ( double pole) switch.

You folks have been over generous, but I cant understand

because I am not electrical,  BUT I would like to use some lighted

toggles for cutting accesories of or on, while trains are operational

all accessories have been wired to a 8 post block from Radio shack

MY ???? is after I go to the fuse, will the way you folks wire stuff up

allow this to be possible,  say ability to cut 1 accessory off, which probably

wont happen, I plan on keeping everything lit up !!
