Hi this is my first post so please go easy, any help would be greatly appreciated.
As a home project I am trying to make table lamp with a dimmer switch. I have purchased a lampholder (http://www.spares2you.co.uk/E27-Threaded-Nickel-Plated-Lampholder) along with a range of pots with variable resistance all w/switches (see http://www.lorlin.co.uk/PDF/MDST.pdf).
I plan keep things as simple as possible to start. I'm using a 60w incadescent light bulb (ES/E27 fitting to match lampholder) and the lamp will run off the mains which in the UK is 240v supply (so running at about 0.25amps) The mains cable I have at the moment (plugged for UK use) comes as live (brown), negative (blue) and earth (yellow/green) - I plan to use a 1amp fuse.
I have read here that pots shouldn't be used as dimmers certainly not running directly off mains, however this pot seems to be designed specifically for this. If you read the specs it is rated for mains and is indeed marketed as one (see "MDST Main Switch + Potentiometer" on the following webpage: http://www.lorlin.co.uk/products.php)
If it is ok to use, my initial question relates to the correct wiring of the Rotary Dimmer Switch (Potentiometer w/switch) and the lampholder. (Please see images attached.)
From reading a little about the wiring of pots my current understanding is to wire the ground should go to point 1, 3 should go to the input of the lampholder with 2 (the middle) receiving the output of the lampholder. Is this correct? Should I continue the earth up to the lampholder's earth? more importantly the two connections on the back of the pot w switch (4&5) what are they and how should they be wired. My initial research shows these are to do with the on/off capacity so I cannot simply wire it as a pot.
All and any help would be greatly appreciated.
