Abstract
Abstract An electrical shock free submersible, remote control switch assembly for controlling the operation of electrically powered apparatus used with swimming pools, spas and the like is disclosed. The switch assembly includes a permanent magnet actuated reed switch mounted in a battery powered, low voltage electrical circuit. The low voltage circuit, in turn, is optically coupled by an opto-isolator to a relay circuit, which is used to open and close the high voltage circuit powering the electrical pumps, lights, blowers, etc. at the pool or spa.
