Ok just to ease my worries, I have started on my control panel and all the cutsout have been made tonight. Now I have to start wiring it all up. Going for one PID, one pump and one element manual on/off. I have some arcoswitch 5503 switches that I will be using, 230V 10 amps (NZ mains power is 230V 3 wire - live, neutral, ground). Now I just want to check with someone on how to wire the lit switches.
Datasheet 5503 - http://www.arcolectric.co.uk/PDFS/catalogue/Pages/P024-025%7CRockerSwitches_171.pdf
Now I was thinking I need to wire as follows:
Pin 1: Load
Pin 2: Line
Pin 3: Neutral
Is this right? I am wanting the swtich to illuminate when on.
