Many of the smaller relays you would want to use have limited on times --
i.e. you wouldn't want to use them as a toggle replacement. If you were to
go down this path make sure you read the data sheets closely.
Once upon a time I was looking at how I could replace multi-pole switches
with spdt, and relays were on the table until I found this out. For most
applications good analog switches (e.g. DG*) are sufficient. In my case
V104 fets did well for the rest.
