Multi-purpose condensate shut-off switch with maintenance port accessory

A multi-purpose float switch assembly for use in-line with a main fluid discharge line connected to a fluid-producing system, to shut off the system when blockage of the main fluid discharge line occurs so that fluid in the main fluid discharge line will be prevented from backing up and damaging the system producing it, said assembly comprising:

• a tubular member with opposing ends and an interior fluid-diverting member;
• a housing having a top surface and an open bottom end, said housing depending from said tubular member and in fluid communication therewith, with said open bottom end being positioned lower than said tubular member, said housing also being positioned relative to said tubular member so that said interior fluid-diverting member prevents said fluid communication between said tubular member and said housing during routine fluid flow in the associated main fluid discharge line when no blockage occurs;
• watertight closure means adapted for sealing said open bottom end of said housing;
• a shaft with an upper threaded portion;
• fastening means adapted for removably securing said shaft in a fixed position centrally within said housing;
• a float switch body concentric with said shaft and positioned for free movement along said shaft;
• and
• stop means adapted for removable attachment to said shaft and maintaining said float switch body on said shaft prior to upward float switch body deployment 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 assembly is adjusted in advance of deployment via said fastening means and said stop means according to a threshold fluid level pre-determined to pose a risk of harm to the fluid-producing system so that when electrical wires are connected between said float switch body and the fluid-producing system, and an amount of fluid accumulates in said housing to exceed the pre-determined threshold fluid level, said float switch body is caused to rise sufficiently to activate a signal that is sent via the connected electrical wires to the fluid-producing system to shut it off before it suffers any harm.
