Zusammenfassung:The present invention describes a de-energizing electrical safety circuit for appliances, in particular dryer machines wherein said circuit controls power supplied from a power source, via a power cord comprising a neutral line and at least one live input line connected to a neutral line and at least one charge powered line, respectively. The de-energizing electrical safety circuit comprises at least one normally open thermostat connected to two switches corresponding to a neutral line and a charge powered line; at least one thermostat is mounted within the cabinet external to the drum. The excess heat in the cabinet closes at least one thermostat thus closing the circuit and allowing the power to flow between the neutral line and the charge powered line causing a short circuit in at least one thermostat and then opening the switches and thereby achieving a complete de-energizing of the dryer machine.
