Little Giant 599123 72" Lead Overflow Safety Switch

The Little Giant 599123 Condensate Overflow Safety Switch 72" Lead is liquid-level sensing equipment used to indicate that there is condensate in HVAC systems. It is a float system that either closes or opens an electrical circuit when water reaches a predetermined height to signal a regulating system to manage the potential of overflow. The switch is mounted in the second drain pan or condensate line and hardwired to the safety circuit of the unit. In heat pumps and air conditioning, it assists in avoiding water damage by providing a regulated signal in HVAC systems.
