Abstract
A flow switch includes a straight, rigid paddle arm and a hub formed mid-length of the paddle arm. An elongate cylindrical member and an elongate paddle handle are formed integrally with the hub and extend from the hub in opposite radial directions. A cylindrical magnet is disposed within a hollow interior of the cylindrical member. A flat paddle is formed integrally with the elongate paddle handle at a radially outermost end of the paddle handle. A transparent top housing houses a flat magnet that attracts the cylindrical magnet and causes the paddle arm to pivot into a position of repose. The cylindrical magnet pivots away from the position of repose into close proximity with a reed switch when the strength of the fluid flow exceeds the magnetic attraction. The reed switch is housed in the top housing in diametrically opposed relation to the flat magnet.
