An improved rain switch includes a tubular L-shaped housing having an enclosed compartment in one arm in which an electrical switch is contained and an apertured compartment in the other arm in which a moisture absorptive assembly is contained. When mounted on a building with the apertured arm parallel to the ground, the electrical switch will be located to one side of the apertured arm and is not prone to coming into contact with any of the rain water passing through the device. Thus, a non-sealed electrical switch can be used. In addition, the housing is snap fit to the building and the electrical switch is releasably contained on a slide member received in the housing to ease switch replacement. A cover also hides a threaded adjusting cap to prevent unauthorized adjustment for how much water is required to be absorbed before the electrical switch is actuated.
