Abstract
A swimming pool user warning system which warns as to the presence of a would-be unauthorized user of a swimming pool comprising, in combination, an electrical warning alarm, a normally open electrical switch and a compressible air-filled hose having both a normal undepressed condition and an actuated depressed condition. The hose is constructed in relation to the switch such that the latter is maintained open as long as the former is in its undepressed condition and such that the latter is closed upon any part of the former being actuated to its depressed condition. A mounting for the hose for an outdoor swimming pool is provided so that the hose is actuated to its depressed condition by the weight or force of such user, whereby to give off an alarm warning of his presence.
