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"...
