[sdiy] Signal relays

[John Blacet]

There are much better analog switches around these days. You need to
determine the maximum error that you can live with and perhaps look at
some Maxim parts.

Relays can be found in DIP size packages with relatively low current
consumption, but the analog switch uses almost no current for
switching....
