Query on current rating of switch for a fluorescent tube

[silverman166]

Is a 1amp switch OK for switching a single 3' standard fluorescent light, please?

I've come across one which would suit my application (automatic switching on wardrobe doors), but it says it's not suitable for fluorescent lights. I can only assume it's to do with startup current (?).

Out of interest, what would be the startup current?

It is probably more to do with the load type - fluorescents are an inductive load whereas your normal filament lamps are resistive.
As it says it isn't suitable for fluorescents then it isn't suitable.

starting current depends on lamp type and ballast type.

Old magnetic ballasts will have a huge startup rush, burn out a 1 amp switch in no time.

But newer T5 electronic units are more controlled and would probably be ok on a 1 amp switch. And more efficient.

If in doubt use a relay.

Is a 1amp switch

I would be more worried about the voltage rating of this switch.

My query really stemmed from the fact that I had seen the same switch (240V incidentally) from two sources, only one of which stated the unsuitability for fluorescents. This is what the ad stated.

IP rating: IP20
> * Code: XS63W, CSWW
> * 1A, 240V mains voltage
> * Current: 1A
> * Supply Voltage: 240V
> * Momentary push switch, normally on, push for off.
> * 2 mm depression required for operation
> * 5.5 mm total travel
> * Dimensions: 45 mm x 34 mm x 20 mm
> * Not suitable for fluorescent.

When asked, the source which had not given the warning wasn't really sure, hence my original question.

This is the manufaturer of the switch: http://www.eterna-lighting.co.uk/productinfo.asp?product=XS63W
nothing there or in the manual about fluorescent lighting.
However at only 1A rating, it is very likely that a magnetic ballast will cause damage to the switch.

Do you really want a magnetic ballast fluorescent in a wardrobe anyway - many seconds and much flickering every time it switches on, with the inevitable hum from the ballast unit resonating throughout the cabinet?
A HF ballast would give instant start and no flicker, plus the tube will last much longer. If you already have the light fitting, it can easily be converted using one of these: http://www.screwfix.com/prods/40067
