Battery driven light timer

[Wightsparks]

How hard can it be? Looking for a nice simple solution..

Light circuit comes directly from MCB on large single/3ph distribution board.
1 industrial wall light switch, no sockets for a N nearby.
I want these lights to be on/off on a 12hr cycle.

I can run a bypass out of the light switch to a timer/relay but it would have to be battery driven as there is not a N handy - If I can find such a switch. Better would be a timer built into an MCB but if such a thing exists I am yet to find it.

Ideas please!

Could you not use a small 400 - 24v transformer to supply a din rail timer and use that to switch the lighting circuit

The issue with a DIN rail timer is the distribution board looks like this

So the MCBs that sit on the rail are connected directly to the busbar - no access for a din rail unit with connections at both ends - that would be too easy!

fit a timer next to the db in an enclosure

How about swapping the light switch for one of those with a timer built in

Great Bob - where did you find that? I could only find ones to fit over a domestic switch.

This runs off one AAA cell lasts for at least a year had mine since we built the house 20 years ago, runs 3 outside lights easy BST GMT adjustment & multi mode there is info but dont know if they are still available.
When we did the extension it became redundant, yours for the postage, you might have to spring for a new battery though
