Rain Switches are designed to over-ride automatic controllers if there has been sufficient rain to make watering unnecessary.
Rain switches are placed in an open spot (away from sprinkers) where it can catch rain and over-ride the electric irrigation controller if a certain amount of rain has fallen.

The Hunter Rain-Clik, with its unique Quick Response feature, can command a controller to shut off immediately not after a 15mm- or a 30mm of rain, but right when it starts to rain. And, unlike any of its competitors, the Rain-Clik can be mounted in a variety of ways: on a rain gutter, on conduit, with a telescoping extension to bring the unit away from an eave, or in the standard method on a flat vertical surface like a wall or fence.
