Mechanical rotary head switch offers high-reliability underwater

My experience with these is great at first, but eventually the magnet deteriorates,. Are you sealing the magnets from exposure?

 

[Wibble]

Magnets seem to "rust" after repeated exposure to salt water. The Paralenz ring fell apart and needed replacing; heater switch is rotting and getting intermittent; another brand's rotary magnet switch would get extremely stiff with sediment in the seawater.

By far the most reliable switches in my experience are the piezoelectric switches used by Shearwater and many other torch manufacturers.

The "mechanical rotary head switch" that Orcatorch is referring to is a simple tighten to turn on, unscrew to turn off mechanism that is the same as backup torches from decades past. The D511 even will operate with 3 C-cells like proper backups should.
