Abstract
Switching apparatus for an electric iron control circuit includes a control switch assembly having a commutator switch and an on/off switch, including a pair of conductive members mounted on an insulating base. Each of the conductive members includes a plurality of conductive fingers interleaved so as to maintain electrical isolation between the conductive members. A rotary contact geared to the temperature control of an iron includes a contact member which alternately bridges and isolates the conductive fingers such that movement of the temperature select knob creates an interrupting signal between terminals connected to the conductive members. When the movable contact is in a predetermined position, a leaf contact is separated from a fixed contact so as to establish an on/off switch control. The base is pivotally mounted to the housing of the iron. A start switch includes a switch case having a pair of conductive resilient leaves normally electrically isolated and a switch button movably mounted in a switch case such that the movement of the switch button is operative to momentarily contact the two leaves to provide a start signal. The start switch is captured between the housing…
