Gary,
I, too, misspoke.  It was Norm's that sells the Brak-D-Lay that we are using
in our rotator control boxes at our club station.  There's a picture, albeit
somewhat small, at http://www.rotordoc.com/sales.html  If you copy it to a
Word sheet or image app, you can drag it larger and blurrily (?) see there
are a number of discrete components adjacent to the relay housing.

We be talking about two different designs!  :-)
