Panel Switches
I'm looking for some switches to control various things in the plane. I need some switches that can carry 20A. I like these, but they only carry 6A. I also found these, but the paddle is too big. I'd like the first kind with larger current handling ability. Has anybody run across anything similar?

Can you get the smaller switches that look like you want, and have them control a relay that can handle the electrical load that you need?

Second choice
I really like the switches with the long paddles, but I'd never be able to use them. It appears they only come in the SPST variety, and my panel uses several different varieties such as SPST, SPDT, DPDT, DPDT on-off-mom, etc.
In my opinion, all the switches should match for aestetics, but you may disagree.

The switch your looking at is rated at 6 amps @ 125 volts AC. I don't know what the rating would be for 12 volt DC. Maybe someone can help.

20A switches will be big and will probably take a lot of force to switch. I agree with the recommendation to use a regular switch to control a relay. You can mount the relay close to whatever you are switching to save on heavy wire as well.

Hello Henry,
Good looking switches...
Don't know how far along on your RV-7 electrical you are, but the Vertical Power VP-X series of microprocessor controlled Electronic Circuit Breakers only require a few milliamps to ground a processor input to activate a circuit. Use any switch you want with this system.
You might already be familiar with Vertical Power, but if not, have a look here.

I am using the ones in this thread (Post #11). They are 20A DPDT lighted rockers. I actually ran wires to both halves for redundancy. That previous thread mentions where you can get them.

Also, keep in mind that illuminated switches designed for 125 VAC will not "illuminate" with 12VDC.

We liked this fancy switch and that fancy switch. But couldn't find any of the "nice" looking switches that could handle the OFF-fuel pump-prime and the OFF-wig wag-landing functions. Didn't want all fancy and two toggles. Didn't want any relays to fail. went with plane old fashion near fail proof toggle switches...

Put them in otherwise unusable space across the top of the panel...

Thanks for the suggestions. That Honeywell switch looks nice.
It might be best to use relays for those circuits that need a lot of current. I would prefer to have all switches look the same and the relay could be activated by whatever I use for the other circuits.
The Vertical Power system looks interesting. Have people generally had good experience with it? It seems like just another thing that could break and then your whole electrical system is compromised.
