ABSTRACT:
A float type circuit breaker for controlling a valve in a pool which includes a housing having an inlet which permits entry and exit of water as the height of the water changes in the swimming pool. A porous baffle prevents surges of water from entering the pool. A pivoted float within the chamber has a mercury switch mounted therein and arranged to complete the circuit to actuate the swimming pool valve when the water has drained from the chamber permitting the float to pivot downwardly therein. A skirt is provided on the housing to permit a motor driven pool sweep to pass thereover.
