Light switch ampage
3 Answers
I hope to use a small inline on/off switch to replace a broken switch in the two-wire flex on a reading lamp. The lamp has 3 GU 10 50W bulbs. The instruction leaflet with the new switch states a maximum load of 2 amps. Can I use the switch for the light and, if so, what level of fuse should I use in the light plug? Thanks.

For more on marking an answer as the "Best Answer", please visit our FAQ.Each 50W bulb takes about 0.2 amps. So that's 0.6 amps, which is fine.
The fuse in the plug of a table lamp should be 3 amps.
The way it is calculated is Watts = Volts x Amps
Since the mains voltage is 250 (or thereabouts), you can see how I worked out that each bulb of 50W uses 0.2 amps, since a 250W appliance uses 1.0 amps.
