UK Domestic extractor fan wiring into a timer

[Steve A]

Hi all
Please could you offer some advice on wiring a 6" bathroom extractor fan.
I've got a stylish surface mounted momentary wall switch and would like to incorporate a 30 min timer.
So I'm looking for a relay that requires a pulse to initiate and run on.
I would rather keep the current switch than purchase a replacement switch with integrated timer
Many thanks in advance
Steve

The above will give a delayed supply starting from the moment the momentary switch is released.

Does your fan have connections for a permanent (L) plus switched (L) from the momentary switch? Make/ Model No?

Is there not a timer module specifically for that fan, that can be purchased as an add-on (or rather 'add-in' module)?

Hi
The connections are only for a permanent live
I could have bought the same model with a timer, but didn't think I would need it at the time.... hindsight again. Wonderful thing

This is a touch timer (you don't need that bit) which also can be activated by a pulse from the type of switch you have. The time on is selected by internal dip switches. You might have to house it in a box in a bathroom which wouldn't be a problem as you are not wanting to use the touch timer bit
