REFLECTOR:Panel Switches

[Tom Martino]

This may be obvious to many ... but it is important enough to emphasize:

It is very important to pay attention to the ratings on the switches.
So many switch makers boast of 200+ voltage capacity ... but it is for
AC current.  If you use AC switches in DC circuits, they will not last
long because DC current is much more load than AC.

It is very difficult to find adequate DC switches.  They should be rated
as 12VDC along with the amperage rating you need.  I also suggest silver
contacts.

I'm wiring up my panel, and I'm looking for recommendations on power
switches.  I don't plan to use a prefab switch/power unit, and have
already
completed my breaker panel.

I want to install rocker switches for various lights (NAV, landing,
etc.) on
the main panel, and rockers for engine functions (mags, starter, fuel
pump,
etc.) on the overhead panel.  I would like the switches to have a
lighted
label and a power indicator light.

I also need push buttons for the stick and panel mounted switches such
as
PTT, autopilot, COM flip, etc.

I did find an interesting looking item by Carling Technologies
(www.carlingtech.com) called the Contura.  This is an attractive, sealed
switch with LED lighting for both label and status.  It's rated 20A at
12VDC.  DigiKey has it available.

Should I stick with sealed switches (marine type)?

Besides obvious sources like Spruce and Chief, any tips on sources?
