Abstract
A toggle switch of the type used on the casing of a camera or intercom device solves the problem of moisture entering the casing through the switch to thereby damage the electronic circuitry, cause rust, mildew and other damage. The exterior of the switch housing is watertight by reason of a turn nut compressing an O ring. The interior of the toggle switch handle housing is made watertight, while still permitting toggle motion, by an elongated seal of solid cross section engaging the outer face of the bulbous portion of the handle and a second elongated seal of solid cross section engaging the inner face of the bulbous portion.
