Abstract
A flow indicator switch system comprising a body having a cavity therein, a first magnetic member pivotally connected to the body and extending into the cavity, a second magnetic member pivotally connected to the body, and a fiberoptic connector arranged about the body for receiving at least one optical fiber. The first magnetic member has a portion that extends beyond the body. A magnet is affixed to the first magnetic member on the end within the body and a paddle is affixed to the other end extending beyond the body. A spring is arranged about the exterior of the first magnetic member. The second member is magnetically interactive with the first magnetic member within the cavity of the body. The second magnetic member has a reflective surface extending therefrom. This reflective surface is generally adjacent the fiberoptic connector and is movable between a first and second position in correspondence to the existence of a fluid flow acting on the paddle.
