Avionics (Radio Problem) Narrowed Down... I Think???

Most avionics designers shy away from really exotic and hard to find stuff.
If this is a simple relay and somebody can come up with a pinout for it, you
can easily modify an off the shelf relay to do the job. It may even have a
Rat Schlock part number on it !

He mentioned a past problem he had with the relay switch in his audio
panel, and we slid my panel out to take a look... There is a relay
switch, labeled: AMF Potter Brumfield with a part number of:
R40-E1-X4. We popped out that switch, and he carefully tried to open
it up with his pocket knife. He got it half-way out, but didn't want
to force it, so re-inserted it, but also made a visual inspection for
any obvious signs of defect. Nothing obvious was visible.



relays are commonly called relay switches. soda = soda pop = pop = cokes

Excuse me, "Robet", but after 46 years in the biz you'd think I would know
of whence I speak. Because I like to give advice that is correct, I ask for
confirmation of things I don't understand. I don't understand "relay
switch" because I've never heard of it. It is neither common nor
conventional.

If you can't add anything to the problem/solution except pedantry, butt the
hell out.

I've seen switches. I've never seen a relay switch.

you knew what the poster meant by relay switch, you were just being a
asshole trying to embarrass a layperson for calling it a relay switch
instead of simply a relay- pompous ass. nontechnical persons like
myself, the poster incorrectly use the term from time to time....deal
with it.

In what part of the world? I've been an EE for 20 years and I've never
heard of a device called a relay switch. Maybe it is common somewhere
in the world, but not in the USA.

Matt I doubt many EE would call it a relay switch. I live in the
southeast (coalfields) and have heard non-technical people (myself
included) use the term "relay" and "relay switch" interchangeably most
of my life. Incorrectly so, I take it. I don't know where the poster is
from so I can't speak for him/her. I do want to stress that I am
layperson in electronics and have heard the term only used by like persons.

Come visit the coalfields... we likely have many words you won't hear
anywhere else in the U.S.!

I've got less years than Jim but more than Matt in the gulf states
oilfield onshore/offshore (Texas to Florida and the Caribbean) as a
tech. This was the first time I've heard the term "relay switch" by even
"non-technical people"...

It could be slang, but I'm not making it up. Google search actually
turned up a few.
http://www.nema.org/prod/be/enclosur.../relay-switch/
http://www.extensivemods.com/modules...howpage&pid=74 - 16k -
http://www.quasarelectronics.com/3126.htm
and here are some harvard doods that designs them:

Optimal Design of a MEMS Relay Switch
Authors: M.P. Brenner, J. Lang, J. Li, J. Qiu and A. Slocum
Affilation: Harvard University, USA
Pages: 214 - 217

They are for microelectromechanical devices, so I guess it's used (by
us)a little out of context.

I avoid Google and Yahoo, just because...

http://www.nema.org/prod/be/enclosur.../relay-switch/

Has links that loop. I surmise that they have enclosures for relays and
switches from the listed manufacturers...

http://www.extensivemods.com/modules...howpage&pid=74 - 16k -

Switches 12 volts, has a 2 amp limit... No relay is visible...

http://www.quasarelectronics.com/3126.htm

Looks to be a SPDT Relay... All relays "switch" between NO and/or NC
contacts... A switch does just that between Open & Closed states...
