What is this switch/timer?
 

Hi
Moved into house 2 weeks ago. There is a switch inside next to the front
door for an outside light. It has a flap that slides down and has a rotary
dial with 0,2,4,6 and 8 around it and a turnable knob saying 'Early' one way
and 'Late' the other.

What is it and how does it work?. It has no manufacturer, part number or
instructions on it. The switch turns the light on/off whatever the settings.

Many thanks

Sounds like a light switch countdown timer that will turn the light off
after the set interval. Try setting it to 2, with the light on, and see if
it turns the light off after 2 hours. It may be faulty.

Sounds like the controls of our security light. It uses a PIR to detect
daylight levels, as well as detecting movement. The first dial could
indicate the time after movement detection that the light with remain on.
The early/late dial could adjust the dawn/dusk light levels that trigger
activation of the light (so during the day the light cannot be triggered).

It may have a run-in period when first switched on. To test it, set the time
to the lowest setting, and the other dial to 'early'. This should mean that
the light will turn off after a few seconds after detecting movement, and
that the detector is active all the time. Then wait after switch the light
on. After a few minutes warm-up, it should turn off. You can them test how
easily triggered it is, etc.

Probably a day/night sensor with a delay.

Pay no attention to that man behind the curtain.

I've got one of those, made by Smiths.
It's a security light switch which senses dusk and turns on a light for
a set period.
Wait until it's just getting to dusk and adjust "early/late" until the
light just comes on.
It WON'T work with low-energy bulbs, although you can fit an additional
mod.
Actually, it doesn't work too well anyway because any house-lights
(particularly the one it switches on) shining on the sensor confuses it
totally, so I replaced mine with a 24-hour timer and "got one of those"
in the first sentence should prepend "in a box somewhere".
For instructions see...
