I haven't read any of the datasheets yet on the photomos relays cited by
@Harald Kapp, but just the name leads me to believe these are "ideal" interfaces between the real world and any electronic processor. As for the AQH2223, as Harold mentioned these are photo-coupled, zero-crossing, triac switches. If you don't need that functionality, why specify this component? Choosing which component to use based on price instead of functionality is not a rational way to design anything, and it seldom works with electronics. Used auto parts, maybe; electronics, no. This is not to say I haven't found some rare, exotic, or spiffy electronic component and attempted to design some neat-o impressive circuit around it...
Burroughs beam-switching electronic-counter tubes come to mind... but almost invariably I discover there is a more appropriate component for the task and only nostalgia leads me on.
