Re:GLASTARNET:Switch Ratings.
On the subject of Gold Plated Switch Contacts,if any of you are giving
them serious thoughts then please be aware that are about to spend some Big
Bucks.Good quality switches , circuit breakers , fuses , relays ,
relays , and wire,etc,are available at most of the major avionics and parts
distributors such as EDMO, ASI,
COOPER, HAWKINS and many more. It is true you can expect to pay a little
more but the difference in quality justifies price difference. In reference
to Digi-Key products you can get quality parts from them but you really
need to be product wise to determine what to buy and what not to buy.In
reference to Radio Shack switches I have personally tested just about
everything they have hanging on their walls.There ratings are true BUT the
rating is based on the switch being energized and why have a switch if you
have to keep it in the ON position.
On the subject of Circuit Breakers as opposed to Fuses, I go with the
Major manufacturers and opt for circuit breakers.It is a lot easier to spot
a tripped breaker than a fuse behind a cap or buried somewhere in
the wiring harness. BTW in Re: a previous posting about Rick Nelson's DC3
catching fire because of repeated resets of a breaker most Engineers and
Technicians agree that you should reset a breaker or replace a fuse ONCE,if
it blows again you should know you have a problem.Another not so well known
fact is the fuse or breaker is there to protect the wiring and not the
equipment it is wired to.
On the subject of Wire,don't cause yourselves problems by using cheap
wire.Tefsel or an equivalant is only pennies more per foot.
On the subject of switches rated at 110 volts AC versus 12 volts without
getting into the entricies of OHMS Law just take a look at a High Voltage
transmission line that carries say 28000 volts. For simplicity say it is a
half inch in diameter.How big would it be if the voltage were 110 volts and
serving the same number of users?
Previous comments are not a flame to anyone but just information.
