I suppose it's useful for switches that turn on when hot, i.e the MERC expands to complete the circuit. Other than that, it doesn't have much more use in electronics than water.
Mercury is in the electronics category for a few reasons. The first as @therocketeer states is that it is used for heat sensors. The second, is it is considered an indestructible metal which is also in the electronics category.
Then why isn't INSL in the electronics category? I know it's too late to move it, I'd just like to know why. Or maybe you could just put it in both categories.

It isn't too late to move, they just didn't feel like it. Mostly because it isn't that important...
