A float switch made from plastic and impervious to corrosion, with improvements over the prior art including a more responsive operation resulting from use of a wide float switch body and a closely fitting housing that allow rapid shut-off of condensate production after collection of only a very small amount of fluid, a small housing dimension for easy installation in the small areas used for air conditioning system air handlers, a removable bottom cap for easy debris removal as well as float switch body adjustment for changing conditions, a housing design that allows operation without air vent holes in the housing, and anti-rotation features that stabilize the level orientation of the float switch body needed for proper operation after installation. By its quick and reliable response, the switch promotes use and longevity of energy efficient air conditioners without concern for the increased condensate produced, protecting the environment and energy resources.

I claim: 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. 2. The assembly of claim 1 further comprising a connecting accessory with a hollow interior adapted for fluid communication, opposing ends, and a first leveling means attached to one of said opposing ends adapted for positioning said shaft in an upright orientation for unimpeded vertical movement of said float switch body along said shaft, and wherein said outwardly depending extension further comprises a second leveling means that is complementary in configuration to said first leveling means. 3. The assembly of claim 2 further comprising a threaded sleeve configured for secure watertight connection of said first leveling means to said second leveling means. 4. The assembly of claim 3 wherein said closure means is selected from a groups consisting of caps having female threads, closures having male threads, and closures having male threads and an inner wall. 5. The assembly of claim 2 wherein said connecting accessory is selected from a group consisting of connecting accessories having opposing ends each with a male threaded configuration, connecting accessories having one end with a male threaded configuration and an opposed end with a non-threaded configuration, connecting accessories having a central non-slip mechanical-assist tool engagement configuration adapted to facilitate rotation for threaded connection, connecting accessories having one end with a male threaded configuration and an opposed end with an enlarged non-threaded configuration, connecting accessories having more than two openings for in-line adaptation with a central threaded configuration adapted for connection to said extension on said housing, and connecting accessories having more than two openings and an end cap for auxiliary adaptation. 6. The assembly of claim 5 further comprising at least two of said connecting accessories. 7. The assembly of claim 5 further comprising a threaded sleeve configured for secure watertight connection of said first leveling means to said second leveling means, and wherein said threaded configuration on said connecting accessories, said extension, and said sleeve comprise the type of finer fittings used in standard threaded pipe connections. 8. The assembly of claim 5 wherein said non-threaded ends have a bonded connection to a discharge line. 9. The assembly of claim 1 wherein said fastening means comprises at least one lock-nut. 10. The assembly of claim 1 further comprising an o-ring configured for watertight sealing of said closure means to said housing. 11. The assembly of claim 1 wherein said shaft has a top opening configured for the passage of electrical wires. 12. The assembly of claim 1 further comprising an angled clean-out accessory configured for in series connection with said assembly in a fluid discharge line, said angled clean-out accessory having an enlarged threaded opening configured for the additional of fluids therethrough without the need for a funnel to prevent airlock that blocks fluid entry, said angled clean-out accessory also having an easily removable closure means for said enlarged threaded opening.
