Rangemaster Leisure 110 electric - hob switch wiring diagram?

Just bought a used one and had to replace the front left hob switch - no problem getting at the old one but although the new one is definitely the correct part the layout of the connectors has changed!
On the old switch there ar 2 connectors side by side at right angles at the bottom labelled 4A to which the blue/white and blue wires go. On the new switch while there is a 4A connector it is "on its own" without a second one close by so I am unsure where the blue/white and blue wires go. The red/yellow and brown are the same on the new as old.
Any suggestions as to which connectors the blue/white and blue wires go to?
