Abstract:
1. A multi-purpose float switch assembly for use in association with an auxiliary fluid discharge line connected to a fluid producing system that also has a main fluid discharge line, to shut off the system when fluid flow in the auxiliary discharge line is impeded and poses a risk of the fluid in the main fluid discharge line backing up into the system and causing damage, said assembly comprising: a housing having an open bottom end, an enlarged upper portion, an opening centrally through said top surface, and an extension outwardly depending from said housing with a widened upper end and distal end with a threaded configuration; watertight closure means adapted for sealing said open bottom end of said housing; a shaft with a threaded top portion positioned to extend through said central opening in said enlarged upper portion of said housing, fastening means adapted for removably securing said shaft to said enlarged upper portion of said housing; a float switch body concentric with said shaft and positioned for free movement along said shaft; stop means adapted for removable attachment to said shaft in a position lower than the discharge line and maintaining said float switch body on said shaft by blocking downward movement of said float switch body beyond the position where said stop means is attached to said shaft; and whereby the amount of upward vertical movement of said float switch body needed to activate a signal for shutting off the fluid producing system in fluid communication with said system is adjusted with said fastening means and said stop means so that when electrical wires are connected between said float switch body and the fluid producing system, and a predetermined level of fluid accumulates in said housing sufficient to elevate said float switch body and cause a signal to be sent via the electrical wires to the fluid producing system, the system is shut off and the risk of damage to the system from fluid back up is avoided.
