Control device for mounting on electrically heated articles of apparel

An integrated hand-operable compact control device for mounting in electrically heated articles of apparel for controlling power to heating wires secured in said articles of apparel, said control device having a finger-operable switch integrated with electronic circuits mounted on a pcb board, said electronic circuits having a communication circuit to interface with a user person to provide message information to said user person a waterproof envelope shields at least a portion of said control device, an input electrical connecting port mounted side-by-side with said finger-operable switch and accessible from outside said waterproof envelope, said input electrical connecting port being configured to magnetically receive and retain an external electrical connector having a conductor cable secured thereto to provide power to said electronic circuits from an external electrical power source, said input electrical connecting port having a magnetically coupling retainer secured in a base wall of a concave cylindrical housing for surrounding an electrical conductor coupling and electrically insulated therewith, a magnet retainer secured to said external electrical connector for magnetic coupling with said magnetically coupling retainer in said concave cylindrical housing of said input electrical connector, said external electrical connector having a cylindrical body for close rotational fit in said concave cylindrical housing of said input electrical connecting port, a central electrical conductor coupling in a flat top face of said cylindrical body surrounded by an electrically shielded magnetically attractable flat metal surface for magnetic coupling retention over said magnetically coupling retainer of said input electrical connecting port with said central electrical conductor coupling conductively engaged with said electrical conductor coupling of said input electrical connecting port;

• said input electrical connecting port and said external connector positioned therein, exhibiting a magnetic coupling force of a predetermined strength permitting rotational planar displacement of said external electrical connector and a resistance to shear forces applied thereto by said conductor cable of said external electrical connector, without separating the magnetic coupling retention force between said input connecting port and said external electrical connector.
