Touch sensor light switch

[Dannydee]

Firstly, I understand normal domestic electrics, but not electronics.
I have a 240v 'capacitance touch sensor' light switch, see I LumoS Luxury Crystal Glass 1 Gang 1 Way Touch On/Off LED Light Switches | eBay The blurb states a minimum load of 3 watts. It works perfectly when used to switch a 15 watt light bulb on and off. However, I wish to use this switch to operate a 240v ventaxia bathroom extractor fan, rated at 4.3 watts and it doesn't work. If I connect both the bulb and the fan, they both work, but not the fan when connected on its own. The extractor fan is to be wired separately to the bathroom lighting, and I don't want to have to switch an additional light bulb on every time I switch the fan on. I'm guessing that I need to add a capacitor or resistor into the circuitry, in parallel with the fan, that will act as a 'substitution' for the light bulb. Please advise.

It's possible that the fan isn't presenting enough load for the capacitive touch switch to operate or it could be an incompatibility with electronics in the fan if there's an internal control board.

Simulating a lamp or bulb by adding a resistor is a bit pointless, a bulb is a resistor when it all boils down to it.

Ok Marvo, thanks for taking the time to reply
