Abstract: The magnetic switch is a plastic unit which is made up of a housing containing three pieces, a slideable magnet holder, a bracket, and a plastic leaf spring. The magnet holder and the bracket include keys and notches to provide positive "on" and "off" positions. The housing is aligned with a mercury wetted switch which is capable of handling large current surges without being damaged, whereby the magnet holder is depressed against the spring bias and slid into either the "on" or the "off" position.A hermetically sealed flashlight which includes the magnetic switch is also described. The flashlight comprises a case which is houses dry cells. A screw-on cap which includes a lens forms a hermetic seal when an O-ring is compressed as the cap is engaged.A reflector mount is aligned with the case using a notch and key system which insures the alignment of the mercury wetted magnetic switch and the housing for the magnet holder.
