Anyone got or used one of the "Ranger 3" electronic timeswitches from
Screwfix, code 12544 (p229 of cat #75). Its the one that fits next to a
normal socket or wall switch plate.
My question is suitability for use with CFL loads, i.e. the
arrangements or otherwise for a neutral connection.
Sometimes such devices are marked as not suitable for CFL loads as they
rely on a dribble of current on the switched live to power themselves.

Same question for a plug-in one, 13481, above on same page.

Screwfix should take a leaf out of Farnell's book and put links to data
sheets / instructions etc for their products. The catalogue and website
descriptions are (of necessity) somewhat short.


I've got them (from B&Q). they are made by Philex (www.philex.co.uk).
Bit of a strange web site, but more info can be found by following the
link Products, Product Range, Electrical, Timers and Plug-in
accessories.

They work with CFL's - they take their power from an AA battery. They
work in parallel(?) to the normal light switch ie you can switch the
light on and off normally, but if the timer says the light is on, you
can't use the switch to turn it off.

Not as good as the type that take their power from the lighting circuit,
but the only thing I could find that woks with fluorescents.
