alright fellas i need one of you electrical geniuses to come through for me....im looking for a toggle switch like the ones you see in nascar to start the car....the kind that are spring loaded and you have to hold them and when released it reverts back to the original position.....since adding my air dog i have noticed on my battery gauge the voltage drops to around 10.5 or so instead of the usual 12 when cold starting....if i sit there and wait for the glow plugs to cycle off the voltage bumps up and the truck starts normally (speed wise) if i dont wait for the gp's to turn off the truck will start but is slow cranking until it speeds up.....i want to add the spring loaded toggle so i can hold the toggle up and cut the power to the airdog while i start the truck and then release the toggle and the airdog powers back up....i know i can just use a static toggle but i figured if i use the spring loaded one it wont get bumped off just when i dont need it to.......

 

Try your local heavy truck dealer. Mack,KW, Freightliner etc. Maybe a otr trailer place too.
good luck!

 

i think i need a: on - momentary off toggle......

 

So you are wanting a center on, momentary contact switch, correct? How many amps?

 

Not sure but I think you need a momentary on then just wire it backwards?

 

i want a 2 position toggle.....the lower position needs to be on....when you hold it up it needs to interrupt the circuit.....20 amp....

i thought about this but will the contacts be on the inside of the toggle switch to work it this way?

 

What you need is a Single Pole Double Throw(SPDT)Off-On-Momentary Off Toggle if you are only controlling one circuit, correct?

 

they all seem to be on-off-momentary on.......

 

So a center on-momentary off, that's a lot easier to find than a OFF-ON-(OFF)

 

I have never seen a switch that the middle is anything other than an off position. Take a look at Newark Electronics or Mouser Electronics

I do have some momentary contact Carling switched Glenn you are more than welcome to one of you would like. I believe that I have about 6 ish of them

 

Here's a Carling version Amazon.com: CARLING TECHNOLOGIES 6FA58-73 Switch,Toggle,SPST: Home Improvement in a quick search, grainger and newark have the same ones.

 

that one is 15A but i have a another question.....momentary is gonna be spring loaded right?

 

Yes. The momentary will return to the maintained position.

And after a little digging I have found some Center on 3 positions from Honeywell. Nothing high amps yet though.

Here is one on Allied's site Honeywell - 32NT91-70 - Sensors, Switches & Relays - Switches - Allied Electronics

 

ok with your help i think i found what im looking for.....is this it?
