Timer switch

[Newbyspark]

Has anyone had a similar problem. Was called to light that didn't work, someone had obviously had a fiddle after it had stopped working as neutral had not been reconnected properly. Anyway sorted that and got light working but when you turn the light off on the timer switch the light flicks on and off very quickly.Can only assume when the bulb blew originally it damaged switch. Any ideas.

What type of lamp is in the fitting?

could be a bit of capacitance in the timer circuitry, discharges through the lamp, causing it to flash briefly.

Only Low energy bulb

And it flashes continuously until you switch it on.

first fit a normal lamp. see if that cure the problem.

Will do, thanks.

Have you tried the output voltage at the fitting? on and then off?

Had this recently with a very old timer, the customer now has a standard on/off switch!

I changed to a normal bulb and its all works fine. Very strange how it worked for months with low energy bulb then had enough. Thanks for advice. Funny how customer was upset I still charged them £20 to go round and sort it out, even though it saved them over £20 for new switch.
