British General IP66 20A 2-Gang 2-Way Weatherproof Outdoor Switch with Neon (66499)

Hi Ma77z1, As long as you don't overload either of the switch mechanisms (they're 20A rated, so it's unlikely you will have 4.8kW on either of them) then there's no operational reason you couldn't do as you propose. One thing to bear in mind is that the switches will only disconnect Live power (because they are light switches really) so you may want to be extra careful around your water feature when it is switched `off' unless you have completely isolated the feed (including the Neutral) upstream of the switch.

Hi ChapelTim, For the indicator to function in Switch Mode without restricting the circuit power you would need a Neutral at the switch position, then you can move the indicator wire from COM to L1/1Way (to be with the Switched Live circuit wire) and remove the link wire from the L2/2Way terminal and terminal block (to be replaced here with the Neutral). Alternatively you could run a low powered circuit _through_ the indicator by moving the COM wire, as above, into the L1/1Way terminal and removing the link wire from the L2/2Way terminal and terminal block (to be replaced here this time with the Switched Live circuit wire) but this does run the risk of either causing the circuit to run under-powered or the indicator light to be `burned-out' in a relatively short time and potentially cut off power to the circuit as a result.

Hi TomKaye, The pre-installed knockouts form part of the tested and certified weatherproof enclosure, you do not need to replace them if you are not using their associated hole(s).

Hi Ashy82, One of the sides of the back-box has a pair of knockouts yes, and as it is perfectly square you can rotate it so that this side is on the bottom as required.

Hi Ashy82, For two of the indicating modes a Neutral is necessary, for the third mode (as the unit is supplied) it is not. On a related note, the indicator can only be wired to one circuit or the other, not both of them.
