Abstract: The present invention relates to a dehumidifier safety cut-off system. This invention is an after-market safety accessory for existing dehumidifiers which operate through the use of a condensate-pump. The safety cut-off system would automatically shut down a dehumidifier in the event of pump failure by disabling the power supply to the dehumidifier. This system would consist of a compact housing with an external power cord, a transformer, a normally closed relay, and a pair of external, low voltage leads that would be connected to the safety float switch leads of the condensate pump. The invention could also feature an alternative version that could be hard wired in place.
