Here's a photo of what I'm dealing with:

It's not really as complex as it appears. There are three lighting circuits feeding the main panel. A number of lights in the house, mostly pathway lighting, are controlled by 24 volt latching relays. Each relay has three terminals that can be connected to any one or several switches located throughout the house. Where it gets complicated is when there are three, or even more low voltage (LV) switches controlling a single light.
With this terminal block I think I'll be able to connect as many as six switches to any one given light. So I'll be able to connect a downstairs light in the kitchen, for example, to an LV switch in the bedroom. Or the garage. It's the ultimate electronic game puzzle!
Anyway, thanks to everyone who chimed in. Several suggestions to be logged for future reference.
