ABSTRACT:
A switch mechanism usable underwater including a cover serving as an exterior member, a shaft member displaceable in a longitudinal direction and fitted into a shaft hole having substantially the same cross-sectional area provided in the cover, an O-ring maintaining a water-tight sliding seal between the shaft member and the shaft hole, and a lever member movable about an axis for moving the shaft member by application of a pressing force applied to the lever member in a first direction against a force of a bias member, the pressing force being applied at a first point which is a first distance from said axis, the lever member engaging the shaft at a second point a second distance from said axis which is less than said first distance to move the lever member in a second direction opposite said first direction when the pressing force is removed.
