I am looking for a simple solid state circuit or IC to switch 5v-10vDC using 240v mains. everything I'm finding is for switching 240v using a lower voltage.

Probably best to reduce the mains voltage to more a manageable and safer level (like 12VAC, or even lower) with a "step-down" transformer.
Rectify (and smooth) that ouput and use that to power your solid state (or whatever) device for controlling whatever DC voltage/current level(s) you wish.
Sorry if I was not clear, this IC / Circuit is to detect if AC is present, so on one side I have 240v mains and on the other a voltage of 5v that want to be swtiched when the 240v is present (I said 5vdc-10vdc in case it fluctuates a little) so when 240v is present I want the 5vdc switching. hope this makes it clearer.
