摘要:
A safety circuit for an electrical iron is provided comprising a double through position sensitive switch having a common contact that is connectable to connect a horizontal position sensing contact and a vertical position sensing contact. When the iron is in use, the common contact will continually shift its contact between the two position sensing contacts, which enables the coupling of power to the heating circuit of the iron. When the iron is placed either horizontally or vertically, a delay timer of a control unit will start to count passage of time. When a preset time has elapsed, the control unit will deactivate the coupling of power to the iron's heating circuit. However, during this period when time is being counted or subsequent to the deactivation of power, if use of the iron is resumed, the control unit delay timer will start to count from the very beginning and the power will be activated again.
