NOTE The off position does not imply an all-pole disconnection.

visibly glowing heating element
heating element that is partly or completely visible from the outside of the appliance and has a temperature of at least 650 °C when the appliance has been operated under normal operation at rated power input until steady conditions have been established

PTC heating element
element intended for heating consisting mainly of positive temperature coefficient resistors that are thermally sensitive and have a rapid non-linear increase in resistance when the temperature is raised through a particular range

user maintenance
