What's best to use to pressure-proof/seal electronics? Glycerine? Mineral oil?

What am I up to:
I have a simple "momentary make" switch lanc controller for my video camera. It has a tiny amount of circuitry but is essentially a plastic disc a bit more than an inch across with a press switch on top and an LED sticking out of the side.

I have cable, I have glands, so getting the signal to the camera is not a problem. My problem is what to do with the switch? Make/bastardise a separate pressure proof box? Replace the switch with a reed? Or seal it in a bag, CL or something and fill with glycerine etc?

Use a reed switch and a magnet on the outside of the camera housing - zero chance of leaks and no messy oils - or are you looking to get the distance provided by the cable?
