An electronic pressing iron having a soleplate and a housing connected to the soleplate is disclosed herein. An electric resistance heating element is mounted in the soleplate for receipt of an alternating current from a suitable source. A temperature control thermostat is connected in series with the electric heating element and is mounted in good heat conduction relationship with the soleplate to control the temperature thereof. A motion and attitude sensing switch is mounted in a handle of the housing and provides a motion signal to a programmable timer also mounted in the handle. A thermal relay mounted in the handle is connected to the programmable timer to receive a time out signal therefrom. When the electronic pressing iron is switched on and is stationary with its soleplate oriented horizontally, for a period of thirty seconds, the programmable timer signals the thermal relay which interrupts the electric current flowing through the heating element. When the electronic pressing iron is resting on its heel rest and is not moved for a period of sixteen minutes, the programmable timer also signals the thermal relay to interrupt electric current flowing through the electric heating element. |
