An electronic device comprising a lens and a selector ring is disclosed. The selector ring is mounted for rotation about the lens and comprises a plurality of tabs projecting inwards towards the lens which engaging with and are held within a tab receiving groove comprising a plurality of spaced notches. Each of the notches is dimensioned to receive one of said tabs. A wave spring positioned between an annular ledge of the lens and the selector ring which biases the plurality of tabs against the groove and such that when each of the plurality of tabs is positioned adjacent a respective one of the notches, the tabs are biased into the notches thereby preventing said selector ring from being rotated. A user disengages the tabs from the notches by pressing said selector ring against the bias of the wave spring, thereby allowing the selector ring to be rotated.

An environmentally protected switch and water activated device using the switch is disclosed. The switch comprises an elongate housing having an open end and divided into a pair of chambers and into which a probe is inserted. When water infiltrates the housing an electrical circuit is completed between the two probes. There is also disclosed a lens/selector assembly comprising a selector ring encircling a lens and a wave spring which biases the selector ring into one of a number of predetermined positions around the lens. Illustratively, a magnet is placed within the selector ring a position of which can be detected by electronics within the lens.
