What I was hoping to find was one tht would go in the regular switch panel in the bus but if not I will install a regular toggle for now. Yes it is a two stage sw with three wires so two pole sw will work. Jerry

I had a Freightliner with a straight 6 and Jakes.  It had two toggle switches with paddle handles.  One was On/Off, the other was 2/4/6 Cylinders (so that you could tailor the amount of braking to fit the conditions).  These were the only toggle switches on that side of the panel, and I didn't have to look down to use them.

If you look in the cockpit of an F-15, you see that the switches and controls are various shapes.  A pilot can tell by touch what each control is.  This is something worth considering.  You may need to adjust (or kill) your Jakes some night in the middle of a cloverleaf, with construction lights in your eyes and Jersey barriers six inches from each side of your coach.  It's a lot better to just reach over and slap both switches down than to fumble around to count the third rocker switch from the left, on the third bank down . . .

F-15's have jake brakes? :o Cool  ;D ;D Is that to slow them on the declines?  ;)
Seriously, this topic brought up a question when I read about the rocker switch with the off in the center position--My understanding on the 8V jake brake was that 'HI' turned on both banks of solenoids and 'LO' only turned on 1 bank. I wired my switch so that 'OFF' is down, 'LO' is in the middle and 'HI' is forward. On 'HI' I have power to both wires. On 'LO' I only have power to 1 wire. Should I have a switch that only powers 1 wire at a time, and if I do that, how do I know which wire for 'HI' and which for 'LO' without taking it out on the road and trial and erroring it?
I don't want to hijack this thread, but now I'm concerned that I might be damaging my jake when I use it by having it wired incorrectly.
Thanks for any clarification on this, Will

you are good, PP.

My preference is off at the bottom, full at the top, middle in the middle.

happy coaching!
