Abstract:
A motor activating circuit device comprising:a power supply source;an overload protector;an auxiliary winding for a motor;an electronic part, wherein said electronic part including:an electronic element having opposite sides and having first and second electrodes which are located on said opposite sides of said electronic element, said electronic element having sidewall portions connecting said opposite sides, the surface of said sidewall portions defining an outer periphery of said electronic element, and said first and second electrodes having respective faces;support means for elastically supporting said electronic element, said support means including first and second contact sections in contact with said first electrode at different positions thereon, and third and fourth contact sections in contact with said second electrode at different positions thereon, wherein said first through fourth contact sections make contact with said electrodes only at selected points, and wherein there is space along the face of said first electrode which separates said first contact section from said second contact section, and there is space along the face of said second electrode which separates said third contact section from said fourth contact section;the entirety of the selected points of the first and fourth contact sections being located closer to said periphery of said electronic element than the entirety of the selected points of the third and second contact sections;said first and fourth contact sections being electrically connected with said first and second electrodes respectively to provide a conductive path for application of power to said electronic element; andthe second and third contact sections being electrically isolated from said first and second electrodes;wherein said first contact section is diagonally disposed from said fourth contact section with said electronic element located therebetween, and said second contact section is diagonally disposed from said third contact section with said electronic element located therebetween, such that a straight line connecting said first contact section and said fourth contact section would intersect a straight line connecting said second contact section and said third contact section, the point of intersection being within the electronic element,said electronic part being connected in series to said auxiliary winding; anda main winding for a motor, said main winding being connected in parallel to said electronic part and said auxiliary winding connected in series;wherein a parallel connection circuit including said main winding, said auxiliary winding, and said electronic part is connected to said power supply source via said overload protector.
