Garden Sentry 12V - Part 8B

As posted pity I didn't have this setup in the front yard for this morning to ambush (scare & wet) White Legs. Anyway in the workshop this morning before it gets too hot to do some more refinements the main one being a system test switch.

It turns out that it's a PIA to setup the motion sprinkler every time it'd going to be used. The sensor LUX has to be turned towards DAY so I can trigger the system to adjust water pressure after which  the LUX control has to be turned back towards NIGHT. If I don't get it right I get sprayed going out to put the lock on the front gates lol.

Went through some of my stuff and found a bag of SPDT Centre Off Rocker Switches.
