Not looking for full home automation, or wifi lights, so figured this was a better forum than Gadgets etc.

I'm looking for a light switch to replace a standard on-off switch, but will only stay in the ON state for a short duration (30 seconds or so).  Basically enough time for a child to transit a hallway, and not need to be reminded to turn the light off after them!!  Ideally the default action would be a short-term ON, but with an option to remain ON.

Had a quick search, but can only find full electronic or 24/7 mechanical programmable ones.

One more thing, as this is a hallway light, there is a switch at each end of the hallway, so that might introduce a challenge, depending on how they are wired.  (And yes I plan to get an electrician to carry out any electrical work)

Actually, thats a nifty idea for bedrooms too and DarthKermit's suggestion of the 648TM is custom enough to do everything required to give people enough time to turn on bedside lights etc.  Very nifty.  (Has to be for $51 (Electrical Direct) though)

PDL also do a PIR module that fits in a faceplate so wouldn't even need to turn the switch on

Hi,
it sounds like you are after a timer?
Have a look at this: http://www.pdl.co.nz/product-details.aspx?rcat=products&catid=1222&id=1841
I have two installed at home, one on a toilet extract (timer set at 3 min) and one on a hot air transfer kit (set at 2hrs). It works like this: press the button, the load is ON indefinetely. Press button again the timer function is activated. There are three modes, what I described is one of them, which suits my application.

You may also try and have a look at Clipsal series 319 of Pneumatic Timers. I would go into a trade store and ask to have a look at it. You just press a large button which gradually comes back. When it does, it will switch the lights off. The speed is adjustable.

I hope this helps.

Hi aucklander,
Yup, DarthKermit pointed me at the same PDL module.  Very nice idea, especially with the different modes to choose from on install.

We have two of these PDL modules for bathroom fans.  They are brilliant and should do exactly what you want (just check the minimum on time).
