The switch has 4 connections , 2 central and 2 on each side, instructions state to connect brown to the central switched terminal but which terminal ( left or right location) does the blue wire fit into. Should this be a direct head to head connection or through the individual terminal?

IF YOU KNOW MAKE AND MODEL OF FAN,
LOOK IT UP ON INTERNET-THERE MAY BE A

This is a tough one. I believe you may have a 2 way switch for the kitchen lights. Here's a link to a site that has a good description of 2 way switches.

In a case like this, I would make sure the breaker is off and use a voltmeter to determine which wires are which. You can do this by testing the wires for voltage and turning the break on and off (I'm not sure how comfortable you are with working with electricity). You can also check for connectivity by seeing which wires run to the lights. Once you know which wires go where, you can then figure out how the wires should go. I would not want to hazard a guess based on the wire colors only. The voltmeter never lies. Hope this helps and good luck!

OK .. the thick black and white are the power for the fan , are there also white wires on the lamp sockets ..??
The thick black wire should connect to the black wire on the switch.
The small black wires connect to the red and blue wire on the switch .. two small black wires each .. that should give you a position for 2 lights , and 4 lights, on the step switch .. but there should be white wires from the lamp sockets connected to the thick white from the fan .

please respond .

dear sir
try to find out first all wire wich type of you shold use ampere meter for testing thise wire .
ampere meter turn into continuty mode and conecect its one lead (wire cable) to your motors black wire and watch the display what is rating there .and write it next wire check and date write like this way check your all 4 wire and now who is high number data its conect to number 1 after that some low conecet number to switch number 2 after that who is lowest conect to number 3 and that black colour wire conect to the L mark then try to start your motor
hope answer the question
thank you

Don't break away the tab.
It sounds like you have Hot wire connected to wrong side of device.

Electricians don't guess, they test.
Separate wires. Turn power ON.
Test each wire to bare ground.
Tester lights up on Hot wire.

Hot connects to brass screw(s). This will feed power into each switch.
Wires going to Load (lights) connect to each silver screw.
