 |
|
I want to use smaller size switches in place of the normal rotary type mag switch. What is minimum current rating/volt rating for such a switch when used with regular mags? Since these ground the mags, it's not clear to me how to size them... any input is appreciated. Thx, Steve.

Steve:
I guess you are considering TWO Single Pole Single Throw (SPST) switches.
Well, all that the switch is doing is supplying a Path to Ground for the 'P' Lead.
What is important is NOT the voltage or current rating but the Mechanical Construction and Reliability.
What I used was two (2) standard SPST 15 Amp switches. Nice solid switches that can handle the abuse you will be giving them. They will not fail because of voltage or current, but they can fail because of abuse.
I would NOT use mini or micro sized switches. Get a switch that has a nice strong SNAP when opened or closed.

Plain vanilla toggle switches are fine. See

Magnetos are not especially "stressful" to their
controlling switches. The standard toggle has been
the ignition switch of choice called out in the z-figures
since day-one irrespective of the ignition system technology.

Bob, thanks for the info. I wanted something more specific, so I called Unison.They said 3A (at) 200V AC is the min rating, for anyone who wants to know.

Which is consistent with what I wrote. Virtually anything you purchase will
be equal to and in most cases better than what Unison calls for.
