Abstract
An electric iron has a printed circuit board mounted to a rear wall in the iron's housing. An operating switch is mounted on the circuit board. The operating switch connects the iron to a source of electrical power when moved by a first manual force and disconnects the iron from the source of electrical power when moved by a second manual force or moved responsive to energization of a solenoid winding.

A control system for selectively connecting and disconnecting an electric iron to a source of electrical power comprising:
- a printed circuit board mounted to a rear wall of a housing of the iron;
- an operating switch mounted on the circuit board including a drive member movable in response to a force being applied thereto;
- an operating knob extending through the housing in close proximity to the rear wall and connected to said drive member for enabling an iron user to apply a manual force on said drive member;
- a pair of spaced electrical contacts and an electrical conductor movably positioned relative to the pair of contacts for selectively completing an electric circuit therebetween when in engagement therewith;
- electrical force applying means electrically connected to said drive member including means for energizing said electrical force applying means to apply an electrical force on said drive member;
- and
- means connecting said drive member to said conductor for moving said conductor relative to said contacts in response to movement of said drive member, said drive member moving said conductor into engagement with said contacts in response to the application of a first manual force on the member through the operating knob and said drive member moving said conductor out of engagement with said contacts selectively in response to the application of said electrical force thereto by said electrical force applying means and in response to the application of a second manual force through said operating knob.
A switch assembly for selectively connecting and disconnecting an electric iron to a source of electrical power comprising:
- a housing formed of electrically non-conductive material having a longitudinally extending bore;
- a solenoid frame formed from electrically non-conductive material and connected to said housing;
- an electrically conductive winding disposed within the frame;
- electrically conductive drive means disposed within an electric field of the winding;
- a pair of spaced electrical contacts;
- an electrical conductor operably connected to said electrically conductive drive means movably positioned relative to the pair of contacts for completing an electrical circuit therebetween when in engagement therewith, said iron being connected to said source of power upon completion of said electrical circuit;
- means connected to said electrically conductive drive means for transmitting a first manual force thereto to move said conductor into engagement with said contacts, said connecting means transmitting a second manual force to move said electrically conductive drive means to disengage said electrical conductor from said contacts;
- and
- means for energizing said winding to move said electrically conductive drive means to disengage said electrical conductor from said contacts.
