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.


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.

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...

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

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