Range cooker wiring

    I have a Britannia range cooker that has peculiar wiring (well, according to me).

    The cooker has two electric ovens and gas hob. Now the two ovens are wired independently of each other, with the larger one has a clock for timing and auto control of the oven. It is controlled be a thermostat and a multi-function switch which controls which element or fan is powered. The neutral for all functions is fed back through a sole contact.

    What I find strange is that the multi-function switch not only switches the live, but also the neutral. Now I cannot see why the neutral would be switched internal to the unit, but maybe there is a reason. The load on any other connector on the switch is 10 amps but is 16 amps through the neutral connection. I would imagine 10 amps is max for that kind of switch - so is likely the N side is overloaded.

    The cooker is fed from a double pole switched isolation cooker feed as per normal for Ireland.

    Now this is an Italian manufactured cooker, so is this an Italian requirement, or is it normal in Irish electric ovens?

    Any ideas?
