Abstract

A power control device is to be used with a pressing iron which includes a soleplate, a housing mounted on the soleplate and provided with a handle, a heating device disposed in the housing and operable so as to heat the soleplate, and a power supplying unit for supplying electric power to the heating device. The power control device includes a switch circuit adapted to connect electrically the heating device and the power supplying unit, an optical sensor unit adapted to be mounted on the handle of the housing, the optical sensor unit generating a first control signal when the handle is released and a second control signal when the handle is gripped, and a timer circuit connected electrically to the switch circuit and the optical sensor unit. The timer circuit receives the first and second control signals from the optical sensor unit and deactivates the switch circuit so as to disconnect the heating device from the power supplying unit upon detection that the handle was continuously released within a predetermined first time period. The timer circuit further deactivates the switch circuit upon detection that the handle was continuously gripped within a predetermined second time period.
