Planning the control panels...

So after much thinking and tinkering with various ideas for planning a control panel I have plumped for good old Excel (well on the Mac so not so old).  Mainly as the other offerings were only for PC or were so complicated that it was going to take days to work out how to even do a basic plan rather than the one I wanted.

Each 'blue' spot is going to be a SPDT switch to allow controller 1 or two control that particular section, the 'yellow' ones being pure on/off isolater switches and the 'red' ones being for either push to make or (on)off(on) switches I have already.

The main panel is just over 1 sheet of A4 in size when printed out properly and to allow enough room from behind to wire the switches up - the fiddle yard one about 3/4 of a landscape piece of A4.
