Replacement for mercury switches?

I was thinking about using a mercury switch for some application
(detecting if a horizontal item is tilted vertically), but understand
that mercury switches are being phased out because they are
environmentally unfriendly and potentially toxic. Does anyone know what
is being used as a replacement to perform the same function? Either in
a electromechanical switch or in a chip (I seem to remember something
about it). Thank you.

Analog Devices makes accelerometer chips that detect x-y-z tilt.

Of course, if you looked in sci.electronics.components where this
sort of question really belongs, you might notice that the same
question was asked there on November 19th, with 14 replies.

This was discussed a couple of weeks ago in sec:

My answer was to stock up on mercury switches.
